 **Build Strategy**:
 
-- 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
-  (no --wrap-mode=nodownload)
+- Uses Arch Linux for up-to-date system packages
+- All dependencies installed via pacman or AUR (no source builds)
+- wlroots installed from official Arch repositories
+- scenefx installed from AUR
 
 **Dependencies**:
 
 - Arch Linux container (archlinux:latest)
 - Meson build system
