/* ══════════════════════════════════════════════════════════════
 * styles/mobile.css — PROMPT-07 Phase 5 (2026-04-17)
 * Mobile responsive overrides for The Doctor Agency ERP.
 *
 * Breakpoints:
 *   ≤ 768px  — sidebar collapses to off-canvas drawer
 *   ≤ 480px  — dense layouts, stack grids
 *   ≤ 375px  — small phone safe rules (text wrapping, min button size)
 *
 * Accessibility:
 *   - All interactive targets ≥ 44×44 px on touch devices
 *   - Form inputs ≥ 16px font-size so iOS does NOT auto-zoom
 *   - Focus outlines preserved
 *
 * Non-destructive: loaded AFTER luxury.css and inline <style> in index.html,
 * overrides via specificity + !important only where necessary to beat inline
 * styles produced by the SPA shell.
