Subject: Profile links paint whole on the first frame: the server renders
 /npub1…, /nprofile1… and /<name> with the kind 0, latest posts, follow counts
 and mentioned faces inlined (stale-while-refresh cache, 2 s budget), the app
 seeds its caches from it, and the big avatar never flashes punk art while a
 lookup runs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A cold visit to a profile link showed a punk, '–' counts and no posts for 9 s.
Server-side relay answers settle once events stop arriving (idle 400 ms)
instead of waiting out a relay that never sends EOSE: a cold build is ~1.9 s.
