 **Build Strategy**:
 
-- All major dependencies (libinput, wayland, wlroots, scenefx) are built from
-  their source repositories
+- Uses Arch Linux for up-to-date system packages (wayland, libinput, etc.)
+- Only builds wlroots and scenefx from source (not available in pacman)
 - Uses `meson subprojects download` before each meson setup to fetch required
   subprojects
 - Allows meson wrap mode for automatic subproject handling
