/* ============================================================
   review.css · the small amount of unique structure the Review page adds on
   top of the aero.css component kit. Everything load-bearing (phase-track,
   timeline, cal-row, aside-card, pattern, two-col, pill, src-tag, callout,
   next-action-card, packet-cta) comes from aero.css unchanged. This file
   only adds the review switcher row, the evidence-chain list, and the
   close-path card so the page reads as one review in depth.

   Dark candidate-branch identity, cyan as the single accent, gold reserved for
   the deliverable (the close-this-review path to the proof packet). Overflow
   safe at 1280px and 375px: every track uses minmax(0, 1fr) and content
   columns set min-width: 0.
