#47 makes skyBackdrop the union of the skies the scenes draw: day 0.238-0.919, dusk
0.017-0.965, night 0.058-0.077. Only night text still clears 4.5:1 on bare sky (5.05);
day falls to 3.71 text / 2.56 link. Everything outside a bubble stays on the plate.

They join the shared plate rule under the scene. The composer's own half-strength
blurred fill goes (its text fell below 4.5:1 in dusk and some auto themes); the
plate has the checked ink. skyTheme.test.ts pins which regions are on the plate.

skyPlate.css.ts joins the room and page headers, the room list, list pages, the
typing and Following bars, non-bubble messages and the room intro to the sign-in
card's opaque --sky-bubble plate, with the plate's ink and link tokens, at all
widths. The estate title bar's own plate goes: the shared header rule covers it.
skyTheme.test.ts pins the link ratios on bare sky as well (day 5.25, night 2.36).

The menu is role=menu with menuitemradio items (aria-checked), the button carries
aria-expanded, focus goes to the checked item on open and back to the button on
close. Over the scene the estate title bar and any non-bubble message sit on the
sign-in card's plate (--sky-bubble) instead of bare sky. skyTheme.test.ts pins the
ink colours and WCAG ratios of the picked themes, measured with the ink clamped
into the sky range as skyState.test.ts does; the pass/fail set is unchanged.

One button beside Find a room opens Auto / Day / Dusk / Night (fits a 320 px bar).
Day and Dusk take Noonday Sky's dark ink, Night Midnight Sky's light ink, Auto
keeps the theme the page would have had; signed-out pages follow the state too.
skyTheme.test.ts checks contrast from the baked tokens: day and night ink clear
AA on bare sky, every container carries its text, links clear AA on the surface,
and dusk text on bare sky does not, so it stays on surfaces.
