Key changes shipping in 0.9.1: - Floating glass panel locks to a single anchored frame (predicted-popover-left ÷ menubar-bottom). No more position drift between the LED-chip path and the gear-popover path; panel is non-draggable. - Tapping menubar piano keys / typing notes plays only — the panel is reserved for explicit triggers (LED chip, gear popover). updatePianoWaveformWindow no longer auto-shows. - Dark-mode piano theme: deep-slate naturals, ROYGBIV chromatic stripes (clipped + glow-confined to the lower half), saturated accent-boost sharps with a backlit-organ shadow. Press inverts sharps to dark slate. Pressed naturals fill with system accent + near-black label. - Caps lock / shift drops uppercase white-key labels 1pt to clear the black-key band. - Mini visualizer chip's hover pill is repainted in the punch-out zone so the bars no longer sit in a dark hole. - MIDI-mode title now reads "MIDI" in both the popover and the floating panel. - New AC web window — small (420×300) glass-chromed WKWebView, traffic-lights hidden, on top across all Spaces, AC's `-` close command bridged via injected userscript. - About panel: shorter (320×340), no duplicate "Menu Band" line, "Version 0.9.1 (91)", icon loader falls back to repo AppIcon.icns for `swift run` builds, AC link anchors the new web window to the right of About.
