Width: - All popover-content widths now reference InstrumentListView.preferred Width (224 px) instead of the previous fixed 248 — the input segmented, update banner, and waveform align to the same 224 px slab as the instrument grid. Floor on preferredContentSize removed; the popover sizes to its actual fitting size, ~248 wide vs the prior 280. Brand → About: - Title row up top no longer carries "Menu Band" + the subtitle. Top row is just the octave control + MIDI switch hugging the right. - About column gains the Menu Band heading + subtitle as its first two lines, then the about body, then the link row. One section instead of two. - "ac" link button restored to verbose "aesthetic.computer". Sonic browse: - Re-enable instrument hover-preview. New MenuBandController.setInstrumentPreview(_:) holds a preview note while the cursor sits on a cell; switching cells stops the old note and starts a new one in the new program. Hover-out releases and restores the committed program. Silent in MIDI mode (DAW handles audio there); the program change still applies so the menubar piano is correct when the user toggles MIDI off. - InstrumentListView.onHover callback wired in the popover. Site: - Bump download cache-buster query string to ?v=0d61fdb. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
