The embedded map drew 340px below its card, and said nothing for the 30s it took

Two faults rega measured in the /embed-test re-shoot at 1440, both on main.

THE MAP SIZED TO THE VIEWPORT, NOT ITS HOST. This element had no :host rule at
all, so it defaulted to display:inline with no height of its own and .gm's
absolute inset:0 resolved against whatever ancestor happened to be positioned:
a 1198x900 canvas inside a 1198x560 embed card, with ~340px including the
attribution drawn below the card and clipped. The attribution is a licence
obligation, so clipping it is not cosmetic. Now :host{height:100%} so a
height-bounded slot decides, with min-height:420px as a floor so an auto-height
host still gets a usable map rather than a zero-height one.

NOTHING SAID IT WAS WORKING. First data paint takes 7-30s under SwiftShader —
161 countries, 33 Indian states, 2,105 dots — and for that whole window the
reader saw an empty basemap, indistinguishable from a broken embed. Adds a
notice that starts visible on the first frame and clears after the LAST paint
(paintAdm1), not on 'load': the style fires 'load' early, so clearing there
would retire the notice during exactly the wait it explains. An error replaces
it rather than stacking, and the error path clears it too, so a failure cannot
leave it spinning forever. role="status", since this is progress and not an
interruption.

connectivity.loading added in all eleven locales; parity, keys-exist,
shadow-css and legend-logical-insets all pass. The notice uses inset-inline, not
left/right: it is translated text and mirrors under ar.
