+## Localization & Culture Management
+
+**Current Architecture:** Blazor WebAssembly (client-side culture management)
+
+### Implementation Details
+
+**Culture Storage:**
+- Culture preference stored in browser's `localStorage` (key: `AppCulture`)
+- Managed by `CultureService.cs` (ReceiverUI/Services)
+- Supported cultures: `de-DE`, `en-US`, `fr-FR`
+
+**Culture Initialization:**
+- **Location:** `Program.cs` (lines 53-57)
+- Sets `CultureInfo.DefaultThreadCurrentCulture/UICulture` **before** app runs
+- **WASM-Safe:** Each user has isolated browser instance
+
+**Language Selector:**
+- **Component:** `LanguageSelector.razor` (ReceiverUI/Shared)
+- Displays flag icon + language name
+- Changes culture via `CultureService.SetCultureAsync()`
+- Navigates with `forceLoad: false` (smooth transition, no page reload)
+
+### ⚠️ MIGRATION WARNING: Blazor Server/Auto
+
+**Current approach is WASM-specific and will break in Server/Auto render modes!**
+
+**Why it breaks:**
+- `Program.cs:53-57` sets **global** `DefaultThreadCurrentCulture`
+- In Server/Auto, one app instance serves **all users**
+- User A selects German → User B sees German too (shared state)
+- Thread-safety issues and culture conflicts
+
+**Migration Checklist (when moving to Server/Auto):**
+
+1. **Remove global culture initialization** from `Program.cs` (lines 53-57)
+   - See detailed warning comment in the code
+
+2. **Add RequestLocalizationMiddleware** (Server-side approach):
+   ```csharp
+   app.UseRequestLocalization(options => {
+       options.SupportedCultures = new[] { "de-DE", "en-US", "fr-FR" };
+       options.SupportedUICultures = options.SupportedCultures;
+       options.RequestCultureProviders.Insert(0, new CookieRequestCultureProvider());
+   });
+   ```
+
+3. **OR** Use **per-circuit culture** (Blazor Server approach):
+   - Store culture in circuit-scoped service
+   - Use `CascadingParameter` to distribute to components
+   - See: https://learn.microsoft.com/aspnet/core/blazor/globalization-localization
+
+4. **Update `LanguageSelector.razor`:**
+   - Remove manual `CultureInfo.DefaultThreadCurrentCulture` assignment
+   - Use middleware/circuit culture provider instead
+
+5. **Update `CultureService.cs`:**
+   - Integrate with Server-side culture provider
+   - May need to store in cookies instead of localStorage
+
+**References:**
+- Microsoft Docs: [Blazor Globalization/Localization](https://learn.microsoft.com/aspnet/core/blazor/globalization-localization)
+- Current implementation: `Program.cs`, `CultureService.cs`, `LanguageSelector.razor`

-    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.
