/* ClearRun catalogue — Trigger Arc demo component
 *
 * Bespoke shared visual identity for the four "something happens →
 * time passes → personal message goes out" pages:
 *   missed-call-text-back, customer-milestones, lapsed-customer, review-request.
 *
 * Three-pane layout (trigger / arc / message). CSS-only animation on a
 * 7s loop. Mobile stacks the panes vertically and rotates the arc.
 *
 * Tokens consumed (from styles.css :root):
 *   --navy, --navy-light, --navy-dark
 *   --accent, --accent-hover, --accent-light
 *   --white, --off-white, --light-grey, --mid-grey
 *   --text, --text-light, --text-on-dark
 *   --radius-sm, --radius-md, --radius-lg
 *   --shadow-sm, --shadow-md
 *
 * Markup is hydrated by trigger-arc.js from data-* attributes on the
 * .trigger-arc-demo root. Animations live purely in this file.
