/* Order Rail — the right-edge column driven by js/rail/rail.js.
 *
 * Isolation (ORDER_RAIL_SPEC §6): every class here is prefixed `rail-`, and the
 * only app hook is the `.app` grid's third column (var(--rail-w) in styles.css).
 * Colours come entirely from the app's own CSS variables, so the rail is
 * theme-aware for free — no palette of its own to keep in sync.
 *
 * Section 1 reuses the existing .confq-card markup (styled in styles.css); the
 * full-screen detail overlay reuses .cook-detail (also styles.css). This file
 * owns only the rail shell, its ticket rows, and the collapse/peek behaviour.
