/* styles/brief.css -- THE SESSION BRIEF (2026-10-26, the owner's session
   brief handoff v1, `docs design/session-brief/`: BR1 / BR1b the brief,
   BR2 a changed day, BR3 "How much, and why", BR4 one exercise). Rebuilt
   in the app's own parts -- calm.css's cards, rows, sheet and Back, the
   kernel's bar -- never the references' markup. Served at
   `/styles/brief.css`. 2026-11-03 (in-session v1 §6, SC2-SC4): the brief
   trimmed -- "Works: …" for the chips, IN ORDER's cards with a thumbnail
   a row (calm.css's `.px-thumb`), SC4 with the picture panel (`.px-panel`)
   -- sizes from the handoff's reference pages.

   NO NEW TOKEN. The session's colour is today.css's `tp-c-*` class on the
   page root (`--sc`); every surface is calm.css's. One stylesheet is one
   namespace: every class here is `br-`. */
