Reject branded/generic share images; hero prefers a clean illustrated story

- og:image enrichment now skips branded/generic share images (BBC 'branded_news'
  with its burned-in logo, NPR 'facebook-default', etc.) and keeps the first
  real article image — so no competitor logo lands on our hero. Cleared the few
  already-stored branded URLs so they re-enrich.
- Hero selection now prefers a gentle + readable story that also HAS a (clean)
  image, falling back to gentle-readable, then gentle. The lead is visual when
  possible, typographic otherwise — never branded.

(The '7 cards' report was a stale browser cache: the brief stores 7 and the
built JS requests 7; a hard refresh shows all seven.)

Tests: branded/generic image rejection (87 total).
