Merge branch 'master' into feat/blazor-receiver-ui

Integrate YARP to forward all /api/** requests from the browser to the backend EnvelopeGenerator.API service. Add Yarp.ReverseProxy package, configure proxy routes and clusters in appsettings.json, and register YARP in Program.cs. Add API base URL configuration and register ReceiverApiClient, LocalizationService, and ReceiverAuthState as scoped services to support both server and client scenarios. This improves API/UI separation and authentication handling.

-# EnvelopeGenerator — Copilot Context Notes (English)
-
-## Purpose
-A digital document signing system. Senders upload PDFs and place signature annotation fields via PSPDFKit (EnvelopeGenerator.Web). Receivers open the document in a Blazor WASM viewer, confirm each signature field via a checkbox overlay, draw/type/upload their signature, and export the stamped PDF.
-
----
-
-## Solution Structure
-
-| Project | Target | Description |
-|---|---|---|
-| `EnvelopeGenerator.API` | net8.0 | ASP.NET Core Web API. Receiver auth (cookie), annotation reading, PDF serving. |
-| `EnvelopeGenerator.ReceiverUI` | net8.0 WASM | Blazor WebAssembly. Receiver UI. YARP proxies API calls. |
-| `EnvelopeGenerator.Web` | net7/8/9 | Razor Pages. Sender UI + PSPDFKit annotation placement. |
-| `EnvelopeGenerator.Application` | multi | MediatR CQRS handlers. |
-| `EnvelopeGenerator.Domain` | multi | Domain models, constants, interfaces. |
-| `EnvelopeGenerator.Infrastructure` | multi | EF Core repos, DB context. |
-| `EnvelopeGenerator.PdfEditor` | multi | iText7 utilities. NOT used in ReceiverUI flow. |
-| `EnvelopeGenerator.DependencyInjection` | multi | DI registration helpers. |
-| VB.NET projects (Service/Form/BBTests) | net462 | Legacy. Do NOT touch. |

-## Key Files
-
-| File | Purpose |
-|---|---|
-| `ReceiverUI/Pages/ReportViewer.razor` | Main receiver page. All signing logic. |
-| `ReceiverUI/wwwroot/js/receiver-signature.js` | JS: checkbox overlay, signature pad (draw/type/image). |
-| `ReceiverUI/wwwroot/fake-data/annotations.json` | Dev-mode fake annotations (YARP proxy target). |
-| `ReceiverUI/Models/AnnotationDto.cs` | Annotation position model. All properties non-nullable. |
-| `ReceiverUI/Services/AnnotationService.cs` | Fetches `List<AnnotationDto>` from API or fake-data. |
-| `ReceiverUI/Services/DocumentService.cs` | Fetches PDF bytes from API. |
-| `ReceiverUI/Services/AuthService.cs` | Manages receiver session cookie. |
-| `API/Controllers/AnnotationController.cs` | GET `api/Annotation/{key}` ? annotation list. |
-| `API/Controllers/DocumentController.cs` | GET `api/Document/{key}` ? PDF bytes. |

-## AnnotationDto — Coordinate System
-
-```
-Unit   : 1/100 inch (DX units) — DevExpress XtraReports native
-Origin : Top-left corner of page
-X      : increases rightward
-Y      : increases downward
-
-A4 in DX units: Width = 827, Height = 1169
-
-Conversions:
-  PSPDFKit (pt, top-left):      xDX = xPsPdf * (100/72)
-  GDPicture (pt, bottom-left):  yDX = (pageHeightPt - yGD - elemHeightPt) * (100/72)
-  DX ? PDF points:              pt  = dx * (72/100)
-```
-
----
-
-## ReceiverUI Signing Flow (ReportViewer.razor)
-
-### On Load (`OnInitializedAsync`)
-1. `AuthService.CheckEnvelopeAccessAsync` ? redirect to login if unauthorized
-2. `AnnotationService.GetAnnotationsAsync` ? fills `_annotations`
-3. `DocumentService.GetDocumentAsync` ? fills `_basePdfBytes` (real mode)
-4. `BuildFreshBaseReport()` ? `XtraReport` for `DxReportViewer`
-
-### Signature Popup
-- Tabs: Draw / Text / Image
-- Fields: full name (required), position (optional), place (required)
-- Saved to `_capturedSignature` record
-- If annotations exist ? popup closes ? JS checkbox overlays installed
-
-### JS Checkbox Overlay (`receiver-signature.js`)
-- `receiverSignature.installAnnotationCheckboxes(annotations, checkedIds, dotNetRef)`
-- One `.annot-sig-cb-wrapper` div per annotation, absolutely positioned over viewer scroll container
-- Position: `left = pageRect.left + ann.x * scaleX`, `top = pageRect.top + ann.y * scaleY`
-  - `scaleX = pagePixelWidth / 827`, `scaleY = pagePixelHeight / 1169`
-- Click ? `dotNetRef.invokeMethodAsync('OnAnnotationToggled', id, checked)`
-
-### Apply Signatures ("Unterschriften anwenden" — `SubmitSignaturesAsync`)
-
-**Real PDF mode (`_basePdfBytes` is set):**
-- Calls `StampSignaturesOnPdf` using **iText7** directly on PDF bytes
-- Coordinate conversion: `xPt = ann.X * (72/100)`, `yPt = pageHeight - ann.Y * (72/100) - sigHeight` (Y flip: DX top-down ? PDF bottom-up)
-- Returns stamped bytes ? loaded into new `XtraReport` with `XRPdfContent`
-- Viewer refreshed with `ViewerKey++`
-
-**Dev/fake mode (`_basePdfBytes` is null):**
-- Falls back to `AddSignatureAtAnnotation` (XtraReports DetailBand + BeforePrint counter)
-- This is intentionally left as a dev fallback only
-
-### Export
-- `reportViewer.ExportToAsync(ExportFormat.Pdf)`
-
----
-
-## StampSignaturesOnPdf — iText7 Implementation
-
-```csharp
-// Located in ReportViewer.razor @code section
-// Called by SubmitSignaturesAsync when _basePdfBytes is available
-
-static byte[] StampSignaturesOnPdf(
-    byte[] sourcePdfBytes, byte[] signatureImageBytes,
-    string signerFullName, string signerPosition, string signaturePlace,
-    IReadOnlyList<AnnotationDto> annotations)
-{
-    // Opens PDF with PdfReader/PdfWriter
-    // For each annotation:
-    //   pageNum = ann.Page (clamped to totalPages)
-    //   xPt = ann.X * (72f/100f)
-    //   imgBottomY = pageHeight - ann.Y * (72f/100f) - sigHeightPt  ? Y-axis flip
-    //   PdfCanvas.AddImageFittedIntoRectangle(imageData, rect, false)
-    //   Separator line at bottom of image
-    //   Canvas text block below separator (font: Helvetica 7pt, color: RGB(73,80,87))
-    // Returns stamped byte[]
-}
-```
-
----
-
-## BuildFreshBaseReport()
-
-```csharp
-// Real PDF mode:
-var report = new XtraReport();
-var detail = new DetailBand();
-report.Bands.Add(detail);
-detail.Controls.Add(new XRPdfContent { Source = _basePdfBytes, GenerateOwnPages = true });
-return report;
-
-// Dev/fake mode: returns pre-built report from ReportStorage
-```

-## Mistakes History — Do NOT Repeat
-
-| Mistake | Why Wrong |
-|---|---|
-| `BottomMarginBand` for per-page signatures | Repeats on every page; Y offset wrong |
-| `imageY = (page-1) * 1169 + ann.Y` | Inflates DetailBand; 35 pages ? 140 pages |
-| `e.Graph?.PrintingSystem` in BeforePrint | `Graph` not on `CancelEventArgs` |
-| `ctrl.Report?.PrintingSystem` | `PrintingSystem` not on `XtraReportBase` in WASM |
-| Adding stamp endpoint to `DocumentController` | Not needed; stamping is done client-side in ReceiverUI |
-| iText7 via API (server-side) | Unnecessary; iText7 runs fine in WASM directly |
-
----
-
-## DevExpress Article (2023-08-28) — Why It Does NOT Apply
-
-The article describes **X.509 cryptographic digital signatures** via `PdfDocumentSigner` + `Pkcs7Signer`.  
-Our use case is **visual/image stamping** at specific page coordinates — different problem, different API.  
-`XRPdfSignature` in the article requires pre-placed fields in the report designer, not runtime coordinates.
-

-
-## Change Log
-
-| Session | Date | Change |
-|---|---|---|
-| 1–3 | — | Core infrastructure: services, YARP proxy, JS overlay, signature pad |
-| 4 | — | `AddSignatureAtAnnotation` with BottomMarginBand — ? repeated on all pages |
-| 5 | — | `BeforePrint` + `e.Graph?.PrintingSystem` — ? compile error |
-| 6 | — | BeforePrint counter — ? correct pattern, wrong band |
-| 7 | — | Switched to DetailBand — ? correct band |
-| 8 | — | `(page-1)*1169+Y` offset — ? 35?140 page inflation |
-| 9 | — | Fixed: `BoundsF.Y = ann.Y` + counter; created COPILOT_CONTEXT.md |
-| 10 | — | Investigated DevExpress article — not applicable to our case |
-| 10 | — | Added iText7 to ReceiverUI; implemented `StampSignaturesOnPdf` — ? deterministic coordinates, no page count side effects |
-| 10 | — | Split COPILOT_CONTEXT.md into COPILOT_CONTEXT_EN.md and COPILOT_CONTEXT_TR.md |

-
-## ReceiverUI ?mzalama Ak??? (ReportViewer.razor)
-
-### Sayfa Yüklenince (`OnInitializedAsync`)
-1. `AuthService.CheckEnvelopeAccessAsync` ? yetkisizse login sayfas?na yönlendir
-2. `AnnotationService.GetAnnotationsAsync` ? `_annotations` listesi dolar
-3. `DocumentService.GetDocumentAsync` ? `_basePdfBytes` dolar (gerçek mod)
-4. `BuildFreshBaseReport()` ? `XtraReport` olu?turulur, `DxReportViewer`'a verilir
-
-### `BuildFreshBaseReport()` Mant???
-```
-_basePdfBytes dolu ? XtraReport + DetailBand + XRPdfContent { GenerateOwnPages = true }
-_basePdfBytes bo? (ForceToUseFakeDocument=true) ? ReportStorage'dan LargeDatasetReport ?ablonu (XtraReport, designer'dan geldi?i gibi)
-```
-
-> NOT: `_basePdfBytes` dal? korunur (gerçek PDF modu). Dev ve test sunucusunda `PredefinedReport` (LargeDatasetReport) `XtraReport` olarak do?rudan kullan?l?r — PDF'e export ED?LMEZ.
-
-### ?mza Popup'? ("Unterschrift erstellen")
-- Sekmeler: Çizim / Yaz? / Resim
-- Alanlar: Ad soyad (zorunlu), pozisyon (opsiyonel), yer (zorunlu)
-- `_capturedSignature` record'una kaydedilir
-- Annotation varsa popup kapan?r ? JS checkbox overlay kurulur
-
-### JS Checkbox Overlay (`receiver-signature.js`)
-- `receiverSignature.installAnnotationCheckboxes(annotations, checkedIds, dotNetRef)` C#'tan ça?r?l?r
-- Her annotation için `.annot-sig-cb-wrapper` div'i, viewer scroll container'?na absolute olarak yerle?tirilir
-- **Koordinat hesab?:** `left = pageRect.left + ann.x * scaleX`, `top = pageRect.top + ann.y * scaleY`
-  - `scaleX = sayfaPixelGeni?li?i / 827`, `scaleY = sayfaPixelYüksekli?i / 1169`
-  - Bu koordinatlar sayfa-relatif ve do?ru çal???yor
-- T?klan?nca `dotNetRef.invokeMethodAsync('OnAnnotationToggled', id, checked)` ça?r?l?r
-
-### ?mza Uygulama ("Unterschriften anwenden" — `SubmitSignaturesAsync`)
-
-**Tek ortak yol (her iki mod):**
-- `SubmitSignaturesAsync` ? `BuildFreshBaseReport()` + `WireAnnotationSignatures(report, _capturedSignature)`
-- `WireAnnotationSignatures` ? `report.AfterPrint` olay?na abone olur
-- Belge olu?unca `report.PrintingSystem.Pages` dolu olur; her annotation için `Pages[ann.Page-1]` sayfas?na:
-  - `ImageBrick { Image = imza görseli, Rect = (ann.X, ann.Y, 230, 70), SizeMode = ZoomImage }`
-  - `TextBrick  { Text = bilgi metni, Rect = (ann.X, ann.Y+75, 230, 65) }`
-  - `Page.AddBrick(brick)` ile bas?l?r
-- Brick `Rect`'leri annotation `X`/`Y` (1/100 inch) ? checkbox overlay ile birebir ayn? koordinat, do?ru sayfa+konum
-- `ViewerKey++` ile viewer yenilenir
-
-**Gerçek PDF modu (`_basePdfBytes` dolu):** Yukar?daki ile ayn?; rapor `XRPdfContent`'ten olu?ur, brick'ler yine `AfterPrint` ile `PrintingSystem.Pages` üzerine bas?l?r.

-## GÖREV 1: ?mza Konum Hatas? (BUG) — ÇÖZÜLDÜ
-
-### Kullan?c?n?n ?ste?i
-Annotation'lardan okunan sayfa ve X/Y koordinatlar?na göre, t?pk? checkbox overlay'ler gibi, imzalar do?ru sayfa ve konumda görünsün. `_basePdfBytes` dal? korunsun; dev/test'te designer ile olu?turulan `PredefinedReport` `XtraReport` olarak do?rudan kullan?lmaya devam etsin (PDF'e export yok).
-
-### ÇÖZÜM (Oturum 12) ?
-`WireAnnotationSignatures` metodu, `report.AfterPrint` olay?nda `report.PrintingSystem.Pages[ann.Page-1].AddBrick(...)` ça??rarak imza görselini (`ImageBrick`) ve bilgi metnini (`TextBrick`) do?rudan hedef sayfaya, annotation `X`/`Y` (1/100 inch) konumunda basar.
-
-**Neden çal???r:**
-- `AfterPrint`, belge tamamen olu?tuktan sonra tetiklenir; `PrintingSystem.Pages` art?k gerçek/nihai sayfalar? içerir.
-- Sayfa indeksleme (`Pages[ann.Page-1]`) band veya veri-sat?r? tekrar?ndan **ba??ms?zd?r** ? `LargeDatasetReport`'un veri-ba?l? `detailBand1` sorununu tamamen atlar.
-- Brick `Rect` koordinatlar? raporun yerel 1/100 inch sistemindedir ? checkbox overlay ile birebir ayn?, do?ru konum.
-- Yeni sayfa eklenmedi?i için sayfa say?s? katlanmaz (35 sayfa ? 35 sayfa).
-
-**Derleme s?ras?nda ö?renilen API gerçekleri:**
-- `PrintOnPage` olay? `e.Page` VERMEZ (yaln?zca `PageIndex`/`PageCount`) ? brick eklenemez. Do?ru olay `AfterPrint` + `PrintingSystem.Pages`.
-- `Page` tipinde `InsertBrick` YOK; do?ru metot `Page.AddBrick(brick)` (brick'in `Rect`'i konumu belirler).
-- `ImageBrick.BorderStyle` tipi `BrickBorderStyle`'dir (`BorderDashStyle` de?il). Border için `Sides` + `BorderColor` kullan?ld?.
-
-### Denenen Eski Çözümler (ba?ar?s?z — referans)
-
-| Deneme | Yakla??m | Sonuç | Ba?ar?s?zl?k Sebebi |
-|---|---|---|---|
-| 1 | `BottomMarginBand` + `XRPictureBox`/`XRLabel` | Her sayfan?n alt?na ç?kt? | Band her sayfada tekrarlan?r, sayfa filtresi yok |
-| 2 | `BeforePrint` + `e.Graph?.PrintingSystem` | Derleme hatas? | `CancelEventArgs`'ta `Graph` yok |
-| 3–6 | `DetailBand` + `BeforePrint` counter | Yanl?? sayfa/konum | ?ablonun `detailBand1`'i veri sat?r? ba??na tetiklenir, sayfa ba??na de?il |
-| 7 | iText7 export/reload döngüsü | 35 ? 70 sayfa | Margin uyu?mazl???, `GenerateOwnPages` sayfalar? böldü |
-| 8 | Fake modda `BottomMarginBand` fallback | Her sayfan?n alt?nda | Koordinat yanl?? |
-
----
-
-## YAPILMAMASI GEREKENLER
-
-| Hata | Neden Yanl?? |
-|---|---|
-| `BottomMarginBand`/`DetailBand` ile sayfa-spesifik imza | Band veri-sat?r?/sayfa ba??na tekrarlan?r, koordinat kayar |
-| `BeforePrint` counter ile sayfa filtresi | Veri-ba?l? raporda sat?r ba??na tetiklenir, güvenilmez |
-| `PrintOnPage` ile brick ekleme | `e.Page` yok; brick eklenemez |
-| `Page.InsertBrick(...)` | Yok; do?ru metot `Page.AddBrick(...)` |
-| iText7 export+reload döngüsü | Margin uyu?mazl???ndan sayfa say?s? katlan?r |
-| ?ablonu PDF'e export edip `XRPdfContent`'e yükleme | ?stenmiyor; designer raporu do?rudan kullan?lmal? |
-| Stamplama için API endpoint ekleme | Gereksiz; brick'ler client'ta bas?l?r |

-## BEKLEYEN D??ER GÖREVLER (Sonraki Chat'te Yap?lacak)
-
-### 2. ?mza Arka Plan? Özelli?i
-?mza görselinin ve bilgilerinin kaplad??? alan kadar, yar? saydam hafif gri opak dikdörtgen arka plan ekle. Böylece imza ve bilgiler arka plandaki metinlerden etkilenmez ve okunur kal?r. (Art?k brick tabanl?: `ImageBrick`/`TextBrick`'in arkas?na bir arka plan `Brick` dikdörtgeni eklenebilir.)
-
-### 3. Checkbox Renk ve Stil ?yile?tirmesi
-Mevcut checkbox'lar?n rengi ve kenarl?klar? çok dikkat çekici. Koyu füme tonlar?nda, desenli, sade ve profesyonel görünümlü bir stil olsun. (`receiver-signature.js` ve ilgili CSS.)
-
-### 4. Sayfa Aç?l???nda Otomatik ?mza Popup'?
-Sayfa aç?l?r aç?lmaz imza popup'? ç?ks?n. "Kay?tl? hiç bir imzan?z yok, tan?mlay?n?z" mesaj? gösterilsin. Kullan?c? imzas?n? tan?mlamadan ilerleyemesin. Mevcut "Unterschrift erstellen" butonu "?mzay? de?i?tir" olarak güncellensin.
-
-### 5. Otomatik ?mza Uygulama
-Kullan?c? tüm checkbox'lar? onaylad??? anda imzalar otomatik olarak uygulanmaya ba?las?n (butona t?klamaya gerek kalmas?n). Sayfan?n üstünde imza say?s? ve imzalanmas? gereken sayfalar hakk?nda bilgi gösterilsin.
-
-### 6. Checkbox - DevExpress Toolbar Pozisyon Uyumsuzlu?u (BUG)
-- Checkbox'lar browser'?n boyut/konumuna neredeyse anl?k tepki veriyor
-- DevExpress toolbar de?i?ikliklerine geç tepki gösteriyor
-- Zoom de?i?ince bazen 2-3 PDF yan yana gelebiliyor; checkbox o konumda do?ru görünüyor ama iki PDF'in yan yana gelmesi kald?r?lmal?
-- `DocumentViewer.razor`'daki `DxDocumentViewer` + `DxDocumentViewerTabPanelSettings` bile?enleri daha uygun olabilir mi? De?erlendirmesi yap?lacak.

-  <!-- 
-    Microsoft ResX Schema 
-    
-    Version 2.0
-    
-    The primary goals of this format is to allow a simple XML format 
-    that is mostly human readable. The generation and parsing of the 
-    various data types are done through the TypeConverter classes 
-    associated with the data types.
-    
-    Example:
-    
-    ... ado.net/XML headers & schema ...
-    <resheader name="resmimetype">text/microsoft-resx</resheader>
-    <resheader name="version">2.0</resheader>
-    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
-    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
-    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
-    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
-    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
-        <value>[base64 mime encoded serialized .NET Framework object]</value>
-    </data>
-    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
-        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
-        <comment>This is a comment</comment>
-    </data>
-                
-    There are any number of "resheader" rows that contain simple 
-    name/value pairs.
-    
-    Each data row contains a name, and value. The row also contains a 
-    type or mimetype. Type corresponds to a .NET class that support 
-    text/value conversion through the TypeConverter architecture. 
-    Classes that don't support this are serialized and stored with the 
-    mimetype set.
-    
-    The mimetype is used for serialized objects, and tells the 
-    ResXResourceReader how to depersist the object. This is currently not 
-    extensible. For a given mimetype the value must be set accordingly:
-    
-    Note - application/x-microsoft.net.object.binary.base64 is the format 
-    that the ResXResourceWriter will generate, however the reader can 
-    read any of the formats listed below.
-    
-    mimetype: application/x-microsoft.net.object.binary.base64
-    value   : The object must be serialized with 
-            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
-            : and then encoded with base64 encoding.
-    
-    mimetype: application/x-microsoft.net.object.soap.base64
-    value   : The object must be serialized with 
-            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
-            : and then encoded with base64 encoding.
-
-    mimetype: application/x-microsoft.net.object.bytearray.base64
-    value   : The object must be serialized into a byte array 
-            : using a System.ComponentModel.TypeConverter
-            : and then encoded with base64 encoding.

-        <h2>1. Allgemeine Informationen</h2>
-        <p>In der heutigen schnelllebigen und zunehmend digitalen Welt, sind personenbezogene Daten eine wichtige
-            Ressource. Ihre Daten sind wertvoll und müssen daher mit der durch diverse Gesetze und Vorschriften (DSGVO,
-            TDDDG, ...) gebotenen Sorgfalt behandelt werden.</p>
-        <p>Als Anbieter von lokalen Lösungen (OnPremise) setzt der Hersteller des signFLOWs, die Digital Data GmbH,
-            einen klaren Schwerpunkt auf Datenschutz und Datensicherheit. Für Sie bedeutet dies, dass nur die nötigsten
-            Daten erhoben und gespeichert werden (Datensparsamkeit bzw. Datenminimierung). Außerdem kommen bei der
-            Verarbeitung aktuelle und als sicher geltende Technologien zum Einsatz.</p>

-        <h2>3. Datenerhebung</h2>
-        <h3>3.1 Die folgenden Kategorien personenbezogener Daten werden verarbeitet</h3>
-        <ul>
-            <li>Namen: Benutzername, Vor- und Zunamen sowie Ihre digitale Unterschrift</li>
-            <li>Kontaktdaten: Telefonnummer, Mobilfunknummer und E-Mail-Adresse</li>
-            <li>Technische Daten: IP-Adresse, Zeitpunkt des Zugriffs oder Zugriffsversuchs</li>
-        </ul>
-
-        <h3>3.2 Ursprung der personenbezogenen Daten</h3>
-        <p>Sie haben die unter 3.1 stehenden Daten vorab an Ihren Geschäftspartner (die verantwortliche Stelle)
-            übermittelt. Diese Übermittlung kann mündlich per Telefon, im persönlichen Kontakt, per E-Mail oder per
-            Kontaktformular geschehen sein.</p>
-        <p>Ihre digitale Signatur übermitteln Sie eigenständig, bei der Unterzeichnung eines Dokuments.</p>
-
-        <h3>3.3 Aufbewahrungsfristen / Speicherungsdauer</h3>
-        <ul>
-            <li>Die automatische E-Mail Korrespondenz wird für 6 Jahre aufbewahrt.</li>
-            <li>Unterzeichnete Verträge werden für die Dauer ihrer Laufzeit + 10 Jahre aufbewahrt.</li>
-            <li>Der technische Vorgang wird in der signFLOW Softwarelösung je nach Dokumentart bzw. Vertragsart
-                unbegrenzt aufbewahrt.</li>
-        </ul>
-        <p>Ihre personenbezogenen Daten werden aber grundsätzlich anonymisiert, wenn:</p>
-        <ul>
-            <li>Der Vertrag ausgelaufen ist und die gesetzliche Aufbewahrungszeit vorbei ist.</li>
-            <li>Der Vertrag von Ihnen abgelehnt wurde bzw. nie unterschrieben wurde.</li>
-        </ul>
-        <p>Die gesetzlichen Grundlagen dieser Aufbewahrungsfristen bieten unter anderen:</p>
-        <ul>
-            <li>Handelsgesetzbuch (HGB)</li>
-            <li>Abgabenordnung (AO)</li>
-            <li>Grundsätze zur ordnungsgemäßen Führung und Aufbewahrung von Büchern, Aufzeichnungen und Unterlagen in
-                elektronischer Form sowie zum Datenzugriff (GoBD)</li>
-        </ul>
-        <p>
-            Abhängig von der spezifischen Dokumentart, kann die Aufbewahrungsfrist variieren. Außerdem können sich
-            Zeiten
-            verlängern, falls Unregelmäßigkeiten auftreten. Z.B.: eine rechtliche Auseinandersetzung droht oder aktuell
-            läuft.
-        </p>
-
-        <h3>3.4 Verarbeitungszweck</h3>
-        <p>Die unter 3.1 definierten personenbezogenen Daten werden verarbeitet um:</p>
-        <ul>
-            <li>Den technisch notwendigen Prozess abzubilden bzw. anbieten zu können.</li>
-            <li>Damit Sie als Endbenutzer in der Lage sind, ein zu unterzeichnendes Dokument, digital zu unterschreiben,
-                ist die Feststellung der Identität des Antragstellers, Antragsprüfung und -abwicklung, Abrechnung sowie
-                die Wahrung der Dokumentationspflichten notwendig.</li>
-        </ul>
-        <p>In Einzelfällen werden Daten zur Fehlerbehebung insbesondere bei Supportanfragen von der IT-Abteilung
-            gesondert behandelt oder ggf. an den Hersteller weitergegeben.</p>
-        <p>Im Zuge der Maßnahmen zur Sicherstellung der Informationssicherheit, insbesondere zur Identifizierung und
-            Abwehr von Angriffen, sowie zur Durchführung interner und externer Audits, der Exportkontrolle und der
-            Prüfung von Sanktionslisten, erfolgt ebenfalls eine Datenverarbeitung. Bei Anfragen gemäß §8 Abs. 2 VDG
-            werden die entsprechenden Informationen an die zuständigen Stellen übermittelt.</p>
-
-        <h3>3.5 Rechtmäßigkeit der Verarbeitung</h3>
-        <p>Ihre Daten werden auf Grundlage einer sich anbahnenden oder bereits vorhandenen Geschäftsbeziehung erhoben.
-        </p>
-        <p>Die rechtliche Grundlage für die Übermittlung an zuständige Stellen bildet §8 Abs. 2 VDG. Anfragen von
-            Betroffenen werden gemäß den Artikeln 12 bis 23 der DSGVO sowie den Paragraphen 32 bis 37 des BDSG
-            bearbeitet.</p>
-
-        <h3>3.6 Berechtigte Interessen</h3>
-        <p>Ein berechtigtes Interesse der verantwortlichen Stelle gemäß Art. 6 Abs. 1 lit. f DSGVO besteht in den
-            folgenden Fällen:</p>
-        <p>Es werden Maßnahmen zur Informationssicherheit ergriffen, die sowohl präventive technische als auch
-            organisatorische Maßnahmen sowie die Behandlung von Vorfällen umfassen. Ziel ist es, potenzielle Schäden für
-            das Unternehmen, die von der Datenverarbeitung betroffenen Personen und die Nutzer der Vertrauensdienste zu
-            bewerten und zu vermeiden.</p>
-
-        <h3>3.7 Erforderlichkeit der Daten</h3>
-        <p>Die erhobenen Daten stellen das Minimum der nötigen Daten zwecks digitaler Unterschrift dar. Ohne die unter
-            3.1 genannten Daten, kann der Dienst nicht betrieben werden.</p>
-        <p>Besonders wichtig ist die Angabe einer Mobilfunknummer oder einer deutschen Festnetznummer, da diese für die
-            Authentifizierung und die Signaturauslösung als zweiter Faktor verwendet wird. Ohne diesen
-            Sicherheitsmechanismus kann der Dienst leider nicht bereitgestellt werden.</p>
-
-        <h3>3.8 Weitergabe von Daten</h3>
-        <p>Eine systemische Übermittlung von Daten findet nicht statt.</p>
-        <p>Daten werden nur in Ausnahmefällen, zwecks Supportleistungen, an den Hersteller weitergegeben. Mit der
-            Hersteller besteht ein gültiger Auftragsdatenverarbeitungsvertrag (AVV), welcher die Sicherheit und
-            Integrität des Umgangs mit Ihren Daten gewährleistet.</p>

-        <p>
-            Beim Besuch bestimmter Seiten kommen temporäre Cookies zum Einsatz, die für die technische Bereitstellung
-            der Dienste notwendig sind. Diese sogenannten Session-Cookies enthalten keine personenbezogenen Daten und
-            werden nach Beendigung der Sitzung automatisch gelöscht. Methoden wie Java-Applets oder Active-X-Controls,
-            die das Nutzerverhalten nachvollziehbar machen könnten, werden nicht verwendet.

-        <h2>3. Data Collection</h2>
-        <h3>3.1 The following categories of personal data are processed</h3>
-        <ul>
-            <li>Names: Username, first and last names as well as your digital signature</li>
-            <li>Contact details: Phone number, mobile phone number, and email address</li>
-            <li>Technical data: IP address, time of access, or access attempts</li>
-        </ul>
-
-        <h3>3.2 Source of the personal data</h3>
-        <p>You have previously provided the data mentioned under 3.1 to your business partner (the responsible entity).
-            This transmission may have occurred verbally over the phone, in personal contact, via email, or via a
-            contact form.</p>
-        <p>You transmit your digital signature independently when signing a document.</p>
-
-        <h3>3.3 Retention periods / Storage duration</h3>
-        <ul>
-            <li>Automatic email correspondence is stored for 6 years.</li>
-            <li>Signed contracts are retained for the duration of their term + 10 years.</li>
-            <li>The technical process is stored in the signFLOW software solution indefinitely, depending on the
-                document or contract type.</li>
-        </ul>
-        <p>Your personal data will generally be anonymized when:</p>
-        <ul>
-            <li>The contract has expired, and the statutory retention period is over.</li>
-            <li>The contract was rejected by you or never signed.</li>
-        </ul>
-        <p>The legal basis for these retention periods includes:</p>
-        <ul>
-            <li>Commercial Code (HGB)</li>
-            <li>Tax Code (AO)</li>
-            <li>Principles for the Proper Keeping and Retention of Books, Records, and Documents in Electronic Form and
-                for Data Access (GoBD)</li>
-        </ul>
-        <p>
-            Depending on the specific type of document, the retention period may vary. Additionally, the periods may be
-            extended in case of irregularities, such as a pending or ongoing legal dispute.
-        </p>
-
-        <h3>3.4 Purpose of processing</h3>
-        <p>The personal data defined under 3.1 is processed to:</p>
-        <ul>
-            <li>Support or provide the technically necessary process.</li>
-            <li>Enable you, as the end user, to sign a document digitally. This requires the identification of the
-                applicant, application verification and processing, billing, and compliance with documentation
-                requirements.</li>
-        </ul>
-        <p>In individual cases, data is processed separately by the IT department, particularly in response to support
-            requests, or possibly forwarded to the manufacturer for further processing.</p>
-        <p>Data processing also occurs to ensure information security, especially for the identification and prevention
-            of attacks, and for conducting internal and external audits, export controls, and sanctions list checks.
-            Information may also be transmitted to the relevant authorities in accordance with Section 8 (2) VDG.</p>
-
-        <h3>3.5 Legality of processing</h3>
-        <p>Your data is collected based on an impending or already existing business relationship.</p>
-        <p>The legal basis for the transmission to competent authorities is Section 8 (2) VDG. Requests from data
-            subjects are processed in accordance with Articles 12 to 23 of the GDPR and Sections 32 to 37 of the Federal
-            Data Protection Act (BDSG).</p>
-
-        <h3>3.6 Legitimate interests</h3>
-        <p>A legitimate interest of the responsible entity in accordance with Article 6 (1) (f) GDPR exists in the
-            following cases:</p>
-        <p>Measures are taken for information security, which include both preventive technical and organizational
-            measures as well as incident handling. The aim is to assess and avoid potential harm to the company, the
-            individuals affected by data processing, and the users of trust services.</p>
-
-        <h3>3.7 Necessity of data</h3>
-        <p>The collected data represents the minimum necessary for the digital signature. Without the data mentioned
-            under 3.1, the service cannot be operated.</p>
-        <p>It is particularly important to provide a mobile number or a German landline number, as this is used for
-            authentication and signature triggering as a second factor. Without this security mechanism, the service
-            cannot be provided.</p>
-
-        <h3>3.8 Data transfer</h3>
-        <p>Systematic data transmission does not take place.</p>
-        <p>Data is only forwarded to the manufacturer for support services in exceptional cases. A valid data processing
-            agreement (DPA) exists with the manufacturer, which ensures the security and integrity of the handling of
-            your data.</p>

-        <h2>4. Use of Cookies</h2>
-        <p>
-            When visiting certain pages, temporary cookies are used, which are necessary for the technical provision of
-            the services. These so-called session cookies do not contain any personal data and are automatically deleted
-            after the session ends. Methods such as Java applets or Active-X controls that could track user behavior are
-            not used.

-
-        <h3>3.7 Nécessité des données</h3>
-        <p>Les données collectées représentent le minimum nécessaire pour la signature numérique. Sans les données mentionnées en 3.1, le service ne peut pas être opéré.</p>

+description: 'Answer questions about DevExpress UI Components and their APIs using the dxdocs server'
+---
+
+You are a .NET programmer and DevExpress products expert.
+
+You are tasked with answering questions about DevExpress components and their APIs using dxdocs MCP server tools.
+
+For **ANY** question about DevExpress components, use the dxdocs server to construct your answer.
+
+## Workflow:
+1. **Call devexpress_docs_search** to obtain help topics related to the user question
+2. **Call devexpress_docs_get_content** to fetch and read most relevant help topics
+3. **Reflect on obtained content** and how it relates to the question
+4. **Provide a comprehensive answer** based solely on retrieved information
+
+## Constraints:
+- **Use devexpress_docs_search only once per question** to avoid redundant queries
+- When answering questions, **use only information obtained from MCP server tools**
+- **Include code examples** when available in the documentation
+- **Reference specific DevExpress controls and properties** mentioned in the documentation
+- **Invoke version-specific MCP tools** (for example, dxdocs25_1) if a user specifies a version (for example, v25.1)
