menuband: add headless --render-popover (real MenuBandPopoverViewController view tree, chart expanded, --program N, gamepad row hidden) + --render-jam (Looking For Players window); tag gamepadRow so the capture can hide it. bin/app-store-real.mjs composites the real popover/about/jam/menubar onto solid-purple 2880x1800 canvases (Apple logo corner, no taglines, light-filled panels) and stages them into fastlane/screenshots — replacing the old mocked set. slab menubar: ImageGroupPreview opens a GROUP of images as a grid-tiled wall of chromeless glass panels (Preview-free review), Esc/⌘W to dismiss, click-drag to move; wired into the refresh tick beside the pdf/video/frame viewers. bin/slab-images queues a group → $SLAB_HOME/state/open-images.
