beacon is a GTK4 layer-shell notification daemon in the Cosmonaut Shell idiom.
It owns org.freedesktop.Notifications and renders each notification as a
holographic card: scanline/sweep/noise overlay (shared lib/hologram.py) clipped
to a rounded violet holo-glass card, emitted-magenta text, glow-violet frame
(accent + squiggle for critical), materialise-out-of-static intro / dissolve
outro, top-centre stack.
Implements the interactive spec subset: body markup, urgency, replaces_id,
per-urgency timeouts, action pills, icons (name/path/raw), click-to-dismiss, and
the NotificationClosed / ActionInvoked signals.
- scripts/beacon-start.sh: LD_PRELOAD launcher
- autostart.lua: dunst -> beacon
- windowrules.lua: blur layer-rule for the `beacon` namespace (no_anim; it has
its own hologram intro)
