/*
 * Arc 5 War-Dispatch Timeline — Option A (Bare-clock metronome)
 * ----------------------------------------------------------------------------
 * Three visual layers, that's it:
 *   1. The rail (single horizontal line with hour-callouts).
 *   2. 22 small dots, evenly distributed across the rail by minute.
 *   3. 5 accent markers (one per med chapter) — small filled circles.
 *   4. (Optional, after the bar) 1 vertical "now" indicator line.
 *
 * No medallion rings. No lane-stagger. No per-tick HH:MM labels.
 * No rail-edge dots. No meta line below. No mini-title hovering bar.
 * No image wells for medallions.
 *
 * A reader will hold this for less than a second before clicking —
 * the simpler the better. Pure clock, metronome.
 * ----------------------------------------------------------------------------
