cava: add to deps, fix config via temp file

 - Context menus for tray icons with submenu support, network chooser (known available WiFi/ethernet), bluetooth device manager (connect/disconnect, battery levels)
 - Privacy indicators — screenshare and microphone icons pulse red/green when PipeWire detects active video/audio capture streams. Finally, you'll know when your webcam is on, which is more than can be said for most laptop manufacturers
 - 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
-- Screen corner rounding — tiny overlay windows with quarter-circle masks, click-transparent, configurable via `screenRadius` (set to 0 if you prefer your corners sharp and your desktop ugly)
+- 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
+- Overview widgets — clock and date rendered on the background layer, visible in the gaps between workspace rows when niri's overview is active. Always there, never in the way
 - 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
