 Make an explicit pick decision **every run** — the pick is a daily editorial call, not a side effect of publishing reviews:
 
 - **The pick must be uncontroversial — it's the front page.** The homepage hero greets every visitor out of context, so keep it broadly, unmistakably benign. Never pick anything that could read as endorsing or depicting harm: weapons or anything that cuts, burns, or explodes; anything dangerous or injury-prone; how-to's for any of that; horror or disturbing media; or anything that could be taken as a call to negative action. (A knife is a bad pick.) Such items can still be finds and reviews — they just never get the hero. If your strongest candidate trips this, take the strongest one that doesn't, and note the swap in the digest.
-- **No camping gear in the hero.** Camper trailers and other camping equipment never take the pick — they stay eligible as finds and (occasionally) reviews, just not the front page. If the strongest candidate is camping gear, take the strongest one that isn't.

If the strongest candidate is camping gear, take the strongest one that isn't. (Both hero rules restate `EDITORIAL.md` "Content rules" — the charter is the source of truth.)
 - Candidates: reviews graduated this run plus the existing review pool.
 - "Strongest" = best hero visual + broadest audience appeal; when torn, the one whose virtue is most immediately legible from the tile.
 - New reviews usually win (freshness matters on a daily site), but a weak new review must not displace a strong current hero.
