 - Per-module accent colors that change based on state, with animated transitions. Battery blinks when critical and sends desktop notifications, because the robot cares about your hardware more than you do
 - Audio visualizer on album art via cava — because the robot watched too many r/unixporn posts and couldn't help itself
 - Screen corner rounding — tiny overlay windows with quarter-circle masks, click-transparent, configurable via `screenRadius`. The gradient top border curves to match, because the robot has opinions about pixel alignment

 - Weather via wttrbar with configurable arguments and rich HTML tooltips
 - Power menu with lock, suspend, logout, reboot, shutdown
 - Event-driven updates for network, bluetooth, and power profiles via dbus-monitor/nmcli monitor — no more 5-second polling lag
