The grid stays typographic; the hero is the one intentional visual slot. At
brief-build time we fetch a hero-quality image for the daily five that lack one:
- enrich.py reads ONLY a page's <head> og:image/twitter:image and stores just
the URL (never the body).
- SSRF-guarded: http(s) only, 6s timeout, 300KB cap, <=3 manual redirects each
re-validated, and hosts rejected if any resolved address is private, loopback,
link-local, multicast, reserved, or unspecified.
- image_checked_at column caches success AND failure, so an article is never
retried forever.
- Wired into build-brief and cycle (brief items only, only if image missing and
unchecked). Everything else stays metadata-only.
- Verified live: today's five all carry images (feed + enriched).
Tests: og:image parser, head-only scope, IP guard across internal ranges, and
enrich success + failure-caching (85 total).
