- Port the menu's GlitchText chromatic fringe to ActionBar: additive
magenta/cyan icon ghosts, label ghosts with per-slot phase, and a panel
outline ghost that activates during glitch bursts.
- Add a tiled-scanline overlay (1 dark row per pitch) matching CyberOverlay,
configurable via actionbar.scanline with theme.overlay.scanline defaults.
- Replace idleGhost with animation.rgb (idleOffset/burstOffset/idleAlpha/
burstAlpha); level now decays ~90 ms after triggerBurst for the fast-snap
GlitchText feel while slice bars linger.
- Update README, PROJECT_NOTES, and research-builds tests to cover the new
scanline and rgb config keys.
