Resolves #72 ## Description This PR implements the theme toggle mechanism, client-side persistence, and comprehensive light mode style overrides for the mobile reader layout in **NexusReader**. ### Key Changes 1. **ThemeService & State Management**: - Enhanced `ThemeService` with `InitializeAsync` and `ToggleTheme` using JS Interop. - Synchronized theme state changes via `OnThemeChanged` event. 2. **Local Storage Persistence & FOUC Prevention**: - Added client-side script in `App.razor` and MAUI `index.html` to instantly apply `.theme-light` from `localStorage` before prerendering/rendering to prevent a Flash of Unthemed Content (FOUC). - Created `theme.js` containing JS helper methods (`themeInterop.isLightMode`, `themeInterop.setLightMode`) to interface with `localStorage` and `document.documentElement` class list. 3. **UI Theme Toggle**: - Added a minimalist glassmorphic theme toggle button in the header of the `ReaderCanvas.razor` with dynamic transitions and icon morphing between sun and moon SVG icons. 4. **Light Mode Stylesheets Overrides**: - Added detailed light mode scoped styles (`.theme-light`) for the `ReaderCanvas` and the bottom-sheet `GlobalIntelligence` AI chat panel, utilizing earthy gray text (`#2d2a26`) on warm paper-like backgrounds (`rgba(244, 241, 234, 0.95)` / `#faf8f5`) to maintain high-quality aesthetic consistency. ### Verification - Solution built successfully without errors (`dotnet build NexusReader.slnx --no-restore`). - Scoped CSS isolation checked and validated for both Web and MAUI contexts. --------- Co-authored-by: Marek Jasiński <jasins.marek@gmail.com> Reviewed-on: #71 Co-authored-by: Antigravity <antigravity@google.com> Co-committed-by: Antigravity <antigravity@google.com>
