- Hero blur fix: brief enrichment now prefers a page's og:image even when a
feed thumbnail exists (feed thumbs are often tiny; the hero is shown large).
Verified: BBC hero upgrades to the 1024px share image, ScienceDaily to 1920px.
- Today is now 'Highlights from Today' — hero + 6 (brief size 7), which also
makes the secondary grid a balanced 3+3 instead of an orphaned 3+1.
- Replace now excludes every article seen this session (a client-side seen-set),
so it never cycles back to something already shown.
- New session History panel (this tab only, no account): lists everything seen,
including swapped-away stories, so they stay recoverable. Persistent
history/favorites are tabled for sign-in later.
Tests: og:image upgrade of an existing feed image (86 total).

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).
