  Project:    Musick Radio — portal pages shared styles
  Version:    3.0.0
  Date:       2026-05-16
  Author:     Brendan Faulds + Claude (Anthropic Opus 4.7 1M)
  Changelog:
    3.0.0 — 2026-05-16 — initial v3 portal stylesheet
  Constraint: no-scroll on both pages. The agreement-box on radio-confirm
              is the single explicit scroll exception (per spec §1, §4.2).
