"""
NexusOS action-icon generator.

Builds the icons the XFCE logoff dialog (xfce4-session-logout) and the
Whisker menu command buttons request — shutdown / reboot / log-out /
suspend / hibernate / switch-user / lock-screen / settings — in the
NexusOS palette (white glyph on a deep-purple disc with a lime ring).

Emits one SVG per icon into actions/, rasterizes to
~/.icons/NexusOS/<size>/actions/<name>.png at 16/22/24/32/48/64/128,
then writes the alias copies (xfsm-*, system-suspend-hibernate, and the
settings-manager app-icon names that Whisker's Settings button uses).

Run:    python3 build_actions.py            # SVGs + PNGs + aliases
        python3 build_actions.py --svg-only # just rewrite SVGs
