menuband landing: drop window chrome for floating glass cards
Remove the faux Tiger window (titlebar, traffic lights, pinstripe, white
plate) and the icon's vibrancy plate + dock reflection. Hero and panels
become independent backdrop-blurred cards on the sky, gaps between them
revealing a now-multicolored music-note drift. Wordmark switches to an
Apple Garamond italic stack (falling back to Hoefler Text on stock macOS).
