   review.css — Reviewer Mode: drawer, hub, report, print
   DEMONSTRATION ARTEFACT
   Additive stylesheet. It styles only rv-* classes plus the reviewer page, so
   it cannot re-style the five-act presentation. Calm audit hierarchy: quiet
   panels, readable tables, no animation beyond the existing fade.
