/* Surface: First-protocol presentation · the first-cycle moment (Brief 30 / Wave 3).
 *
 * Scoped to #screen-first-protocol to prevent bleed into other screens. All
 * colors / fonts / radii via var(--...) tokens per ADR-0003 — no inline hex, no
 * new tokens. Touch targets >= 44pt per Capacitor mobile rules.
 *
 * Mockup of record (visual reference): experiential-direction-synthesis-final/
 * first-protocol-5-1.warm-stone.html. CTO-ratified deviations (ADR-0043):
 *   - cycle vocab is "Proposed" at every location (NOT "ACTIVE STACK / Day 1 /
 *     Establish phase") — D2.
 *   - priority-tier accent is UNIFORM Core (single terracotta left border; the
 *     mockup's per-tier opacity variants are not used — engine tier doesn't map) — D3.
 *   - the Rx panel renders medication NAMES only (no dose/timing column) — D1.
