+### Local Arch Package

+Build a local pacman package from the Linux AppImage artifact:
+
+```bash
+bun install
+bun run dist:arch:local
+sudo pacman -U release/arch/cafe-code-*.pkg.tar.zst
+```
+
+To build and install in one step:
+
+```bash
+bun run dist:arch:local -- --install
+```
+
+This is intentionally local packaging only. It does not create AUR metadata or
+publish anything.
