- lib/bio.js: refreshBio() pulls the article intro via the Wikipedia API
(exintro, descriptive UA) and upserts the bio cache; getBio() reads it
with a short accurate static fallback. Page loads NEVER hit Wikipedia.
- crawl route: refreshBio() runs on every 15-min tick (over daily) —
best-effort, a wiki hiccup can't fail the news crawl.
- /api/bio: read-only route.
- page.js: WhoBox renders the live text + 'Full article on Wikipedia' link
+ SOURCE: WIKIPEDIA · UPDATED <date> line.
- tests/bio-test.mjs: fallback + live-refresh + offline degradation.
