The background "didn't change" because the service worker's asset cache
kept serving the previous wallpaper bytes (stale-while-revalidate returns
the cached copy first, and an old worker can outlive a deploy). Both aero
images carry a ?v=3 query now, so a stale cache cannot answer for them.
"Everything should look like the Ask button" is literal: the rail, the
cards, the chips, the segments and the buttons share one recipe - the
pre-blurred wallpaper under a ~15% veil with the bright rim. The blur
bake is regenerated at 640x400 with a shadow lift (gamma 0.86) and a
saturation nudge, so the scene's colours stay vivid instead of washing
to a milky film. The wizard's phone action bar loses Aero's heavy
water-blue slab for the same glass, and nested chrome inside sheets
keeps its flat fills (the sheet itself is the real glass there).
