- Service worker activates new versions immediately (skipWaiting +
clientsClaim). In prompt mode a waiting worker kept serving the previous
build to tabs that never send SKIP_WAITING, so the old UI hit the new API
and showed "Aucun contenu disponible" on every article. Pages already
controlled get a reload toast; lazy chunks missing after a deploy reload
once.
- Reader opens as a large card above the dimmed grid: close with ✕, Escape
or a click beside it; previous/next arrows on the sides (desktop) and a
bottom bar with the next title (all sizes).
- Remove search, the focus banner and decorative headers; plain sentence-
case labels instead of tracked capitals; quieter dashboard header.
- Fix horizontal overflow of cards and reader navigation on phones.
