 # Theme Configuration
 
+> [!info] Amaneh v2.7.0 (commit 56fc84e)
+> The active theme now uses the Amaneh warm-earth palette and the three-font stack (Source Serif 4 / IBM Plex Sans / IBM Plex Mono). MUI component overrides were updated for `Button`, `Card`, `Paper`, `AppBar`, `Chip`, and `Label`. The settings-drawer color-preset swatch picker was simplified to a single Amaneh entry.
+
 The MUI theme is constructed in `frontend/src/theme/index.ts` and composed from option modules in `frontend/src/theme/options/`. The resulting theme is provided at the root layout, wrapped by an RTL-aware emotion cache.
