The globe opens full screen; a phone held sideways keeps its feed

On a phone the globe is a banner above the feed; a tap on it now opens it full screen over everything, with a close
button (Escape closes it too), the focus moving to that button and back, and the feed underneath kept as it was but out
of reach (inert). The camera refits the new shape. Held sideways, a phone (a window at most 30rem tall, the new short:
variant) has no room for the banner: the banner and its toggle give way to a button that opens the globe full screen.
isMobileMedia, which picks the first visit's default, agrees with Tailwind's md now (it was off by one) and counts a
phone held sideways. GlobePanel tells its state (data-globe-state). Phone flows: the globe opens full screen and
closes, and a sideways phone keeps a feed at least 180px tall with no sideways scroll.
