+## Everforest theme
+
+The desktop is themed with [Everforest](https://github.com/sainnhe/everforest)
+(dark, medium; background `#2b3339`):
+
+- `kde` — `Everforest` color scheme, wallpaper, and the lock screen wallpaper
+  (`kscreenlockerrc`). Select the scheme in System Settings > Colors.
+- `ghostty` — `everforest-dark` theme with background opacity and blur (needs
+  KWin's Blur effect on Plasma).
+- `nvim` — LazyVim with `neanias/everforest-nvim` (transparent background) and
+  LSP for zig, python, typescript, rust, go, c and c++.
+- `vscode` — user `settings.json` (Everforest Dark via the
+  `reesew.everforest-theme` extension).
+- `chrome/everforest` — not stowed. Open `chrome://extensions`, enable
+  Developer mode, and Load unpacked on that folder.
+
+The Plasma Login Manager screen is root-owned and can't be stowed: pick the
+wallpaper and sync colors in System Settings > Login Screen after changing the
+scheme. Firefox uses the Everforest Dark Medium theme from addons.mozilla.org.
