/* css/components/regions-tabs.css — TinkyTown SDR Regions sub-tab bar
 * Phase 3 P3.T1. Brand: Fraunces + General Sans + var(--surface-deep)
 * var(--amber) var(--green) var(--green-soft). All colours via var().
 *
 * Visual parity with stage-filter.css (Pipeline) and task-filter.css
 * (Tasks) — same chip size, focus ring, mobile scroll behaviour. The
 * active chip uses the canonical amber accent per spec § 3 (action /
 * energy = amber).
