/* ChainLine POS — Design system unification (Round 4 patch)
 * Loads AFTER pos-styles-v3.css.
 *
 * Purpose:
 *   Resolves the v1/v2/v3 cascade conflict identified in audit Round 4.
 *   - Strips border-radius > 0 from every modal / toast / palette / skeleton / stat-card / kbd
 *   - Strips box-shadow from same
 *   - Strips backdrop-filter
 *   - Maps pos-status-* + pos-toast-* to v1 color tokens (single palette)
 *   - Makes pos-avatar square + tone-palette-driven
 *   - Replaces accent focus ring with neutral, accent on actionable buttons only
 *   - Drops red wash on sidebar active state
 *   - Adds prefers-reduced-motion support
 *   - Adds light-theme variants for v3 tokens
 *   - Adds safe-area-inset handling on mobile bottom nav
 *
 * Apply by adding to index.html AFTER all other stylesheets:
 *   <link rel="stylesheet" href="/pos-styles-unify.css?v=1">
 *
 * Bump the v=1 on each iteration. Once visual parity is confirmed,
 * merge these rules into pos-styles.css and delete this file.
