verify:live: assert the graphite posture, and stop crying wolf at a 503

The stylesheet markers were the previous wave's: white paper and the light
cobalt. They now name what this wave serves — the graphite page, the accent
raised for it, and the second theme — and the retired list gains that wave's
own signature (#101317, #72bdff) plus the prefers-color-scheme branch, which is
gone by construction now that the dark theme IS :root. Its return would mean
the tokens are duplicated again, which is how the print regression got in.

probe() also retries 429/502/503/504. The deploy printed "plex-mono-400.woff2
— HTTP 503" on a file that then served 200 three times in a row: an edge saying
come back later is not a verdict, while a 404 still is — one check asserts one
on purpose.
