-# EnvelopeGenerator - Agent Guide
-
-## Must Read First
-- **`COPILOT_CONTEXT.md`** - Architecture, coordinate systems, migration status
-- **`FORM_APPLICATION_CONTEXT.md`** - Legacy VB.NET features to migrate
-
----
-
-## Documentation Catalog
-
-This section explains every markdown file in the repo: what it contains, why it exists, and when you need it. Read this before deciding which file to open.
-
-### Core Architecture Docs (Active — Always Relevant)
-
-#### `AGENTS.md` ← you are here
-**What:** Authoritative agent/copilot onboarding guide. Covers project structure, route table, render mode rules, coordinate system, API gaps, and common mistakes.
-**Why it exists:** Single source of truth for agents so they don't re-derive architecture from code on every session.
-**When you need it:** Always. Read first on every session.
-**Maintenance:** Update whenever project structure, routes, render modes, or naming conventions change.
-
-#### `COPILOT_CONTEXT.md`
-**What:** Deep-dive architecture reference. Covers the full Blazor Auto hybrid setup, authentication flows (JWT + cookies, per-envelope receiver tokens), service registration patterns, coordinate system proof, and an explicit "prefer Server/Server.Client over old WebUI/ReceiverUI" rule.
-**Why it exists:** Prevents agents from re-deriving or misinterpreting the hybrid SSR+WASM architecture. Also documents coordinate system evidence to prevent regressions (inches vs. points vs. pixels).
-**When you need it:**
-- Implementing any new page or service
-- Debugging auth/cookie issues
-- Any coordinate conversion question
-- Unsure which project a new file should go in
-**Maintenance:** Update when render mode assignments change, new auth schemes are added, or the coordinate system is touched.
-
-#### `FORM_APPLICATION_CONTEXT.md`
-**What:** Comprehensive reverse-engineering of the legacy VB.NET WinForms app (`EnvelopeGenerator.Form`). Documents every form (frmMain, frmEnvelopeEditor, frmFieldEditor, etc.), their UI layout, toolbar actions, data models, coordinate system, and a feature-by-feature migration mapping table to `EnvelopeGenerator.Server`.
-**Why it exists:** The WinForms app is the functional specification for the sender-side web UI. It documents the full intended workflow that is being migrated to Blazor — especially the envelope creation, signature field placement, and dashboard features that are not yet implemented.
-**When you need it:**
-- Implementing any sender-side feature (`/sender`, `/sender/editor`, `/sender/envelope/{id}`)
-- Understanding what a specific toolbar button or form should do
-- Designing API endpoints for sender workflow
-- Checking coordinate system behavior (INCHES proof is here)
-**Maintenance:** Update the mapping table as features are implemented (change `❌ Not implemented` → `✅ Exists`). Do not rename `ReceiverUI` back — it was the old project name; current target is `EnvelopeGenerator.Server`.
-
-#### `RECEIVER_PDF_VIEWER_CONTEXT.md`
-**What:** Detailed technical reference for the receiver-side PDF viewer (`EnvelopeReceiverPage.razor`). Documents the PDF.js integration, signature button rendering, JS interop API (`window.pdfViewer`), signature capture flow, HiDPI/zoom/thumbnail config, and the full component lifecycle.
-**Why it exists:** The receiver PDF viewer is the most complex component in the codebase. This doc prevents agents from misunderstanding the JS↔Blazor boundary, re-implementing already-solved problems (HiDPI, zoom, signature caching), or breaking the signing flow.
-**When you need it:**
-- Working on `EnvelopeReceiverPage.razor` or `pdf-viewer.js`
-- Adding new signature field rendering logic
-- Debugging signature rendering, zoom, or thumbnail issues
-- Implementing sender-side PDF.js overlay (signature field placement) — the receiver side is the reference implementation
-**Maintenance:** Update when `pdf-viewer.js` API changes, new JS interop functions are added, or the signing flow is modified.
-
----
-
-### Deployment Docs
-
-#### `EnvelopeGenerator.Server/EnvelopeGenerator.Server/README.md`
-**What:** IIS publish and deployment guide for `EnvelopeGenerator.Server`. Covers why self-contained publish is required (WASM assembly version strictness), the exact `dotnet publish` command, IIS Application Pool settings (`No Managed Code`), directory structure after publish, and common deployment errors.
-**Why it exists:** Blazor Auto (Server + WASM hybrid) has non-obvious deployment requirements that differ from a standard ASP.NET Core app. Forgetting self-contained publish or using the wrong app pool will break WASM loading in production.
-**When you need it:**
-- Deploying to IIS for the first time
-- Troubleshooting 500 errors on production after deploy
-- Setting up a new deployment environment
-**Maintenance:** Update if the publish target, IIS config, or runtime version changes.
-
----
-
-## Active Architecture (Post-Migration)
-
-**Frontend:** Blazor Auto (Server+WASM hybrid)
-- **EnvelopeGenerator.Server** (Server): `@rendermode InteractiveServer` - PDF viewers requiring DevExpress backend
-- **EnvelopeGenerator.Server.Client** (WASM): `@rendermode InteractiveWebAssembly` - Login, dashboards, business logic
-
-**Backend + API Host:** `EnvelopeGenerator.Server` (ASP.NET Core 8.0, merged Blazor + Web API host)
-
-**Proxy:** YARP in `EnvelopeGenerator.Server` is used for external integrations (for example AuthHub forwarding), not for routing app APIs to `EnvelopeGenerator.API`.
-
-### Deprecated Projects - DO NOT USE
-- `EnvelopeGenerator.ReceiverUI` - Pure WASM (migrated to Server)
-- `EnvelopeGenerator.Web` - Razor Pages (replaced by Server)
-- **VB.NET projects** (`Form`, `Service`, `BBTests`) - Legacy, read-only for reference
-
-## Development Commands
-
-### Run Active Host
-```powershell
-# Terminal - Blazor + Web API host
-cd EnvelopeGenerator.Server\EnvelopeGenerator.Server
-dotnet run
-```
-
-**Critical:** `EnvelopeGenerator.Server` is the active runtime host for both UI and API controllers.
-
-### Build
-```powershell
-dotnet build EnvelopeGenerator.sln
-```
-
-## Project Boundaries
-
-```
-EnvelopeGenerator.Domain/          # Entities (Envelope, Receiver, Document, etc.)
-EnvelopeGenerator.Application/     # MediatR CQRS (Commands, Queries, Handlers)
-EnvelopeGenerator.Infrastructure/  # EF Core, SQL executors, repositories
-EnvelopeGenerator.Server/
-  EnvelopeGenerator.Server/        # Server-side Blazor + API controllers
-    ├─ Components/Pages/           # @rendermode InteractiveServer

-    ├─ Models/                     # DTOs
-```
-
-## Route Structure (Critical)
-
-| Route | File Location | Render Mode | Purpose |
-|-------|--------------|-------------|---------|
-| `/` | `Server.Client/Pages/Index.razor` | WASM | Landing page |
-| `/sender/login` | `Server.Client/Pages/LoginSenderPage.razor` | WASM | Sender auth |
-| `/sender` | `Server/Components/Pages/EnvelopeSenderPage.razor` | **Server** | Sender dashboard |
-| `/sender/editor` | `Server/Components/Pages/EnvelopeSenderEditorPage.razor` | **Server** | Envelope editor + PDF viewer |
-| `/envelope/login/{key}` | `Server.Client/Pages/LoginReceiverPage.razor` | WASM | Receiver auth |
-| `/envelope/{key}` | `Server/Components/Pages/EnvelopeReceiverPage.razor` | **Server** | PDF viewer + signing |
-
-**Rule:** PDF viewers MUST use `@rendermode InteractiveServer` (DevExpress backend requirement). Everything else uses WASM.
-
-## Coordinate System (CRITICAL)
-
-**Database stores INCHES** (GdPicture14 native). Origin: top-left, Y-axis down.
-
-### Conversions
-```csharp
-// Database (INCHES) → PDF Points
-float points = inches * 72;
-
-// Database (INCHES) → DevExpress DX
-float dx = inches * 100;
-
-// PDF.js Pixels → Database (INCHES)
-float inches = (pixelX / canvasWidth) * pageWidthInches;
-```
-
-**A4 Page:** 8.27" wide × 11.69" tall = 595pt × 842pt
-
-**Signature Field Size:** 1.77" × 1.96" (FIXED, do not change)
-
-**Evidence:** See `COPILOT_CONTEXT.md` lines 158-185, `EnvelopeGenerator.Form/frmFieldEditor.vb`
-
-## API Architecture Quirks
-
-### Monolithic Endpoint (Avoid for UI)
-`POST /api/EnvelopeReceiver` - Creates envelope+document+receivers+fields atomically.
-- **Use case:** External API consumers
-- **Not suitable for:** Step-by-step UI workflow (no draft support, no partial updates)
-
-### Sender Workflow Endpoint
-```
-POST /api/Envelope                # Create/update/save/send envelope workflow payload
-DELETE /api/Envelope/{id}         # Delete with reason
-POST /api/Envelope/{id}/document  # Upload PDF
-POST /api/Envelope/{id}/receivers # Add receiver
-POST /api/Envelope/{id}/signature-fields  # Place signature field
-```
-
-See `FORM_APPLICATION_CONTEXT.md` for detailed workflow requirements.
-
-## Status Color Coding
-
-Form app uses DevExpress `CustomDrawCell`. EnvelopeGenerator.Server needs CSS:
-
-```css
-.envelope-row.status-partly-signed { background-color: #81C784; } /* GREEN_300 */
-.envelope-row.status-queued,
-.envelope-row.status-sent { background-color: #FFB74D; } /* ORANGE_300 */
-.envelope-row.status-completed { background-color: #81C784; }
-.envelope-row.status-deleted,
-.envelope-row.status-rejected { background-color: #E57373; } /* RED_300 */
-```
-
-## Configuration
-
-### YARP Proxy (`EnvelopeGenerator.Server/yarp.json`)
-Routes `/api/*`, `/swagger/*`, `/openapi/*`, `/scalar/*` → `https://localhost:8088`
-
-### PDF.js Settings (`EnvelopeGenerator.Server/wwwroot/appsettings.json`)
-```json
-{
-  "PdfViewerOptions": {
-    "ThumbnailBaseScale": 0.75,
-    "ThumbnailEnableHiDPI": true,
-    "MainCanvasEnableHiDPI": true,
-    "ZoomStepPercentage": 5
-  }
-}
-```
-
-### Server Host Config (`EnvelopeGenerator.Server/EnvelopeGenerator.Server/appsettings.json`)
-- `ConnectionStrings:Default` - SQL Server DB
-- `AllowedOrigins` - CORS (includes `http://localhost:5131`, `http://localhost:7192`)
-- `Cache:SignatureCacheExpiration` - Signature persistence timeout
-- `PSPDFKitLicenseKey` - **DEPRECATED** (use PDF.js instead)
-
-## Migration Status
-
-### Complete ✅
-- Receiver login/authentication
-- PDF viewing with PDF.js (HiDPI, zoom, thumbnails)
-- Signature capture (draw/type/image)
-- Signature caching (Redis/SQL)
-- Sender login
-
-### Missing (High Priority) ❌
-- Sender dashboard (`/sender`) - Empty stub
-- Envelope editor (`/sender/envelope/{id}`)
-- Signature field placement tool (PDF.js + draggable overlays)
-- Granular API endpoints (draft, receivers, fields)
-- Master-detail grids for receivers/history
-
-## Common Mistakes (DO NOT REPEAT)
-
-| Mistake | Why Wrong |
-|---------|-----------|
-| Using iText7 in receiver pages | GPL license issue. Use PDF.js overlays. |
-| Using PSPDFKit | Removed from architecture. Use PDF.js + DevExpress. |
-| `@rendermode InteractiveWebAssembly` on PDF viewers | DevExpress DxPdfViewer requires server-side rendering. |
-| Hardcoded quality in PDF.js | Use `appsettings.json` `PdfViewerOptions`. |
-| Coordinates in points/pixels for DB | Database uses INCHES. Convert before save. |
-| `BottomMarginBand` for signatures | Repeats on every page. Use `DetailBand`. |
-
-## Testing
-
-**No automated tests exist yet.**
-
-Manual testing workflow:
-1. Start EnvelopeGenerator.Server (`dotnet run` in `EnvelopeGenerator.Server\EnvelopeGenerator.Server`)
-2. Navigate to `https://localhost:5131` (or check console output for port)
-3. Test sender login at `/sender/login`
-4. Test receiver flow at `/envelope/login/{envelopeKey}`
-
-## Database
-
-**SQL Server** (DD_ECM)
-- Connection string in `EnvelopeGenerator.Server/EnvelopeGenerator.Server/appsettings.json`
-- EF Core migrations NOT used (manual SQL scripts)
-- Stored procedures: `PRSIG_*` prefix
-
-**Key Tables:**
-- `TBSIG_ENVELOPE` - Envelope metadata
-- `TBSIG_ENVELOPE_RECEIVER` - Receiver assignments
-- `TBSIG_DOC_RECEIVER_ELEMENT` - Signature fields (X, Y in INCHES)
-- `TBSIG_RECEIVER` - Receiver registry
-- `TBSIG_DOCUMENT` - PDF binary data
-- `TBSIG_ENVELOPE_HISTORY` - Audit trail
-
-## DevExpress
-
-**License:** Commercial (v25.2.3)
-**Components Used:**
-- `DxGrid` - Master-detail grids
-- `DxPdfViewer` - Server-side PDF rendering
-- `DxPopup` - Modal dialogs
-- `DxToolbar` - Action bars
-- `DxFormLayout` - Forms
-
-**Theme:** Blazing Berry (default)
-
-## JavaScript Interop
-
-**PDF Viewer:** `wwwroot/js/pdf-viewer.js`
-```javascript
-window.pdfViewer = {
-    initialize(canvasId, pdfDataUrl, dotNetRef),
-    renderPage(num),
-    renderSignatureButtons(signatures, pageNum, dotNetRef),
-    applySignature(signatureId, dataUrl, fullName, position, place),
-    zoomIn(), zoomOut(), dispose()
-}
-```
-
-**Signature Pad:** `wwwroot/js/receiver-signature.js`
-```javascript
-window.receiverSignature = {
-    initializeDrawPad(canvasId, dotNetRef),
-    getSignatureDataUrl(canvasId),
-    clearPad(canvasId)
-}
-```
-
-## Multi-Envelope Support
-
-Receivers can login to **multiple envelopes simultaneously** via per-envelope cookies:
-```
-AuthTokenSignFLOWReceiver.{envelopeKey}
-```
-
-Each envelope maintains independent authentication state.
-

-# EnvelopeGenerator — Current Workspace Context
-
-## Purpose
-Digital document signing system for senders and receivers.
-
-- Senders authenticate, view envelope lists, and manage envelope workflows.
-- Receivers authenticate per envelope, open PDFs, create signatures, and apply them in the viewer.
-- The active UI stack is `Blazor Auto` with server-side and WebAssembly render modes.
-- Primary UI/PDF libraries are `DevExpress` and `PDF.js`.
-
----
-
-## Active Application Structure
-
-### Main Host
-**Primary active application:** `EnvelopeGenerator.Server`
-
-`EnvelopeGenerator.Server` is the current runtime host and contains:
-- Blazor server host
-- WebAssembly host integration
-- API controllers
-- authentication/authorization setup
-- Swagger/Scalar setup
-- YARP reverse proxy configuration
-- DevExpress server-side services
-- SQL Server distributed cache setup
-
-### Client Project
-**Client UI project:** `EnvelopeGenerator.Server.Client`
-
-This project contains:
-- WebAssembly-rendered pages
-- client-side services
-- client models and options
-- sender and receiver login flows
-
-### Other Projects
-- `EnvelopeGenerator.Application` — MediatR/CQRS handlers and business logic
-- `EnvelopeGenerator.Domain` — domain models, constants, shared abstractions
-- `EnvelopeGenerator.Infrastructure` — EF Core and infrastructure services
-- `EnvelopeGenerator.PdfEditor` — PDF-related backend utilities
-- `EnvelopeGenerator.API` — deprecated project (no longer part of the active solution/runtime path)
-
-### Legacy / Do Not Touch
-- `EnvelopeGenerator.Service`
-- `EnvelopeGenerator.Form`
-- `EnvelopeGenerator.BBTests`
-- `EnvelopeGenerator.CommonServices`
-
----
-
-## Current Hosting Model
-
-`EnvelopeGenerator.Server/Program.cs` currently configures:
-- `AddRazorComponents()` with both interactive server and interactive WebAssembly components
-- `AddControllers()` and `MapControllers()`
-- JWT authentication for sender and receiver flows
-- cookie authentication
-- authorization policies using `AuthScheme.Sender`, `AuthScheme.Receiver`, `AuthPolicy.Sender`, `AuthPolicy.Receiver`
-- `AddReverseProxy()` with `yarp.json`
-- Swagger / OpenAPI / Scalar
-- distributed SQL Server cache
-- DevExpress Blazor and DevExpress PDF Viewer server-side services
-- request localization middleware
-
-This means the active app is a **merged UI + API host**.
-
----
-
-## Reverse Proxy
-
-**Config file:** `EnvelopeGenerator.Server/EnvelopeGenerator.Server/yarp.json`
-
-Current YARP usage is focused on **AuthHub forwarding**, not a general `/api/* -> EnvelopeGenerator.API` proxy.
-
-Configured routes forward:
-- `POST /api/auth` -> AuthHub `/api/auth/sign-flow`
-- `POST /api/Auth/envelope-receiver/{key}` -> AuthHub `/api/auth/envelope-receiver/{key}?cookie=true`
-
----
-
-## Active Routes and Files
-
-### WebAssembly Pages (`EnvelopeGenerator.Server.Client`)
-| Route | File | Render Mode | Purpose |
-|---|---|---|---|
-| `/` | `EnvelopeGenerator.Server/EnvelopeGenerator.Server.Client/Pages/IndexPage.razor` | WebAssembly | Landing page |
-| `/sender/login` | `EnvelopeGenerator.Server/EnvelopeGenerator.Server.Client/Pages/LoginSenderPage.razor` | WebAssembly | Sender login |
-| `/sender` | `EnvelopeGenerator.Server/EnvelopeGenerator.Server.Client/Pages/EnvelopeSenderPage.razor` | WebAssembly (`prerender: false`) | Sender dashboard |
-| `/envelope/login/{EnvelopeKey}` | `EnvelopeGenerator.Server/EnvelopeGenerator.Server.Client/Pages/LoginReceiverPage.razor` | WebAssembly | Receiver login |
-
-### Server Pages (`EnvelopeGenerator.Server`)
-| Route | File | Render Mode | Purpose |
-|---|---|---|---|
-| `/envelope/{EnvelopeKey}` | `EnvelopeGenerator.Server/EnvelopeGenerator.Server/Components/Pages/EnvelopeReceiverPage.razor` | InteractiveServer | Main receiver PDF viewer and signing page |
-| `/envelope/DxPdfViewer` | `EnvelopeGenerator.Server/EnvelopeGenerator.Server/Components/Pages/EnvelopeReceiverPage_DxPdfViewer.razor` | InteractiveServer | DevExpress PDF Viewer test page |
-| `/envelope/{EnvelopeKey}/DxReportViewer` | `EnvelopeGenerator.Server/EnvelopeGenerator.Server/Components/Pages/EnvelopeReceiverPage_DxReportViewer.razor` | InteractiveServer | DevExpress report-based PDF rendering |
-| `/envelope/Embed` | `EnvelopeGenerator.Server/EnvelopeGenerator.Server/Components/Pages/EnvelopeReceiverPage_embed.razor` | InteractiveServer | Embedded browser PDF view test page |
-
----
-
-## Current API Location
-
-The active application exposes controllers from:
-`EnvelopeGenerator.Server/EnvelopeGenerator.Server/Controllers`
-
-Current controller set includes:
-- `AnnotationController`
-- `AuthController`
-- `CacheController`
-- `ConfigController`
-- `DocumentController`
-- `EmailTemplateController`
-- `EnvelopeController`
-- `EnvelopeReceiverController`
-- `EnvelopeTypeController`
-- `HistoryController`
-- `LocalizationController`
-- `ReadOnlyController`
-- `ReceiverController`
-- `SignatureController`
-- `TfaRegistrationController`
-
-Do not assume API behavior lives in `EnvelopeGenerator.API`; the active merged host contains controller endpoints directly.
-
----
-
-## Authentication Model
-
-### Sender
-Client login page uses `EnvelopeGenerator.Server.Client/Services/AuthService.cs`.
-
-Key sender endpoints:
-- `POST /api/auth?cookie=true` — login
-- `GET /api/auth/check` — current sender access check
-- `POST /api/auth/logout` — logout
-
-### Receiver
-Receiver authentication is **per envelope**.
-
-Key receiver endpoints used by client services:
-- `POST /api/Auth/envelope-receiver/{envelopeKey}` — submit access code
-- `GET /api/auth/check/envelope/{envelopeKey}` — check access
-- `POST /api/auth/logout/envelope/{envelopeKey}` — logout receiver for one envelope
-
-Receiver cookie resolution in server auth uses an envelope-specific cookie name derived from:
-- `AuthTokenSignFLOWReceiver.{envelopeKey}` pattern
-
-### Receiver Server-Side Authorization
-`EnvelopeReceiverPage.razor` does **not** rely on its own API access-check call for page authorization.
-
-It uses:
-- `EnvelopeGenerator.Server/EnvelopeGenerator.Server/Services/EnvelopeReceiverAuthorizationService.cs`
-
-Behavior:
-- tries the current `HttpContext.User`
-- if needed, reads the per-envelope receiver cookie directly
-- validates the JWT with the receiver auth scheme
-- verifies the token subject matches the route envelope key
-
----
-
-## Receiver Page Data Loading
-
-Main server-side page data service:
-- `EnvelopeGenerator.Server/EnvelopeGenerator.Server/Services/EnvelopeReceiverPageDataService.cs`
-
-This service loads directly via MediatR and distributed cache:
-- document bytes
-- receiver envelope data
-- signature placeholders
-- cached signature data
-
-For signature placeholders, the service:
-- reads document receiver elements
-- filters them for the authenticated receiver
-- converts coordinates to `UnitOfLength.Point` before UI use
-
----
-
-## Receiver PDF Viewer
-
-**Main file:** `EnvelopeGenerator.Server/EnvelopeGenerator.Server/Components/Pages/EnvelopeReceiverPage.razor`
-
-Current receiver viewer characteristics:
-- route: `/envelope/{EnvelopeKey}`
-- render mode: `InteractiveServer`
-- PDF rendering: `PDF.js`
-- toolbar: page navigation, zoom, thumbnail toggle, signature navigation, signature reset
-- signature popup: `DxPopup`
-- thumbnail sidebar: resizable and stored in `localStorage`
-
-### JS Assets
-- `EnvelopeGenerator.Server/EnvelopeGenerator.Server/wwwroot/js/pdf-viewer.js`
-- `EnvelopeGenerator.Server/EnvelopeGenerator.Server/wwwroot/js/receiver-signature.js`
-
-### CSS
-- `EnvelopeGenerator.Server/EnvelopeGenerator.Server/wwwroot/css/envelope-viewer.css`
-
-### PDF.js CDN
-- `https://cdnjs.cloudflare.com/ajax/libs/pdf.js/3.11.174/pdf.min.js`
-- `https://cdnjs.cloudflare.com/ajax/libs/pdf.js/3.11.174/pdf_viewer.min.css`
-
----
-
-## Signature Workflow
-
-Receiver signatures are handled as a **viewer overlay workflow**.
-
-### Current behavior
-1. Server-side authorization validates receiver access.
-2. The page loads document bytes, receiver data, signature placeholders, and cached signature state.
-3. If no cached signature exists, the signature popup opens automatically.
-4. Receiver creates signature using one of three tabs:
-   - draw
-   - text
-   - image
-5. Required metadata:
-   - full name
-   - place
-6. Optional metadata:
-   - position
-7. Clicking a signature placeholder applies the signature as a client-side overlay in the PDF viewer.
-
-### Important note
-Although `itext` is referenced by the server project, the current receiver page signing flow is **not PDF stamping-based**. The active receiver UI uses client-side overlay behavior in the viewer.
-
-### Signature DTO
-`EnvelopeGenerator.Server.Client/Models/SignatureCaptureDto.cs`
-
-```csharp
-public sealed record SignatureCaptureDto {
-    public required string DataUrl { get; init; }
-    public required string FullName { get; init; }
-    public string Position { get; init; } = "";
-    public required string Place { get; init; }
-}
-```
-
----
-
-## Signature Cache
-
-### Active cache model
-The current receiver page cache flow is handled directly in the server project through:
-- `EnvelopeReceiverPageDataService`
-- `IDistributedCache`
-- SQL Server distributed cache configuration from `Program.cs`
-
-### Cache key format
-Current server-side key prefix:
-- `envelope-generator.receiver-ui.signature:{receiverSignature}`
-
-This is different from an envelope-key-only cache convention.
-
-### Config
-`EnvelopeGenerator.Server/EnvelopeGenerator.Server/Options/CacheOptions.cs`
-- section name: `Cache`
-- option: `SignatureCacheExpiration`
-
-### Related controller
-A cache API controller also exists in:
-- `EnvelopeGenerator.Server/EnvelopeGenerator.Server/Controllers/CacheController.cs`
-
----
-
-## Sender Dashboard
-
-**Main file:** `EnvelopeGenerator.Server/EnvelopeGenerator.Server.Client/Pages/EnvelopeSenderPage.razor`
-
-Current behavior:
-- checks sender access through `AuthService.CheckSenderAccessAsync()`
-- redirects to `/sender/login` when unauthorized
-- loads envelope list through client `EnvelopeService`
-- separates envelopes into active/completed tabs
-- uses `DevExpress DxGrid`
-
-The sender page is active, but create/edit/delete actions are still marked with TODO behavior in the UI page.
-
----
-
-## Localization
-
-Current server host localization setup in `Program.cs`:
-- supported cultures: `de-DE`, `en-US`
-- request localization middleware is enabled
-- `QueryStringRequestCultureProvider` is added
-- cookie-based localization services are registered via `AddCookieBasedLocalizer()`
-
-Do not assume the old ReceiverUI-only `localStorage` culture approach is the current source of truth for the active host.
-
----
-
-## Coordinate System
-
-### Source data
-Database signature coordinates are still based on:
-- **unit:** inches
-- **origin:** top-left
-- **axes:** X right, Y down
-
-### Relevant conversions
-- inches -> PDF points: `x_pt = x_inches * 72`
-- inches -> DevExpress DX units: `x_dx = x_inches * 100`
-
-### Current receiver page behavior
-The server page data service converts signature placeholders to **points** before sending them into the viewer workflow.
-
-### Unit systems to keep in mind
-| System | Unit | Origin | Y-axis |
-|---|---|---|---|
-| Database | Inches | Top-left | Down |
-| PDF.js display | Pixels | Top-left | Down |
-| PDF points | Points | Depends on PDF model | Depends on consumer |
-| DevExpress DX | 1/100 inch style coordinates | Top-left-oriented usage in this app | Down-oriented usage |

-- Prefer current `Server` / `Server.Client` paths over old `WebUI` / `ReceiverUI` references.
-- Do not use `EnvelopeGenerator.Web` or `EnvelopeGenerator.ReceiverUI` as the primary implementation target unless explicitly asked.
-- Do not modify the legacy VB.NET projects unless explicitly requested.
-- For receiver PDF/signature work, prefer the current `PDF.js`-based flow in `EnvelopeReceiverPage.razor`.
-- For DevExpress PDF viewer issues, remember server-side services are registered in `EnvelopeGenerator.Server`.
