/*
 * QR Timing styles.
 *
 * One responsive stylesheet serves both design variants: "compact" (phones, about 390px wide) and
 * "expanded" (desktop, 1280px). Layouts are built with flex-wrap and auto-fit grids, so they rearrange
 * themselves without media queries.
 *
 * Sections:
 *   1. Design tokens
 *   2. Base and page shell (header, footer, containers)
 *   3. Shared components (eyebrow, buttons, cards)
 *   4. Landing page
 *   5. Check-in page
 *   6. Success and error pages
