/* =============================================================================
 * app-shell.css — MOBILE-ONLY "app style" layout chrome.
 *
 * Adds a native-app feel on phones: a pinned top app-bar, a fixed bottom tab
 * bar (Home · Services · Book · Enquiry · Contact) with an elevated centre
 * "Book" button, a scrollable middle, and a repositioned floating chat bubble.
 *
 * SCOPE: every rule below lives inside `@media (max-width: 920px)` — the same
 * breakpoint the site already uses for mobile. Desktop / tablet-wide layouts
 * are never touched. Nothing here changes PHP logic, data, or behaviour; it is
 * purely presentational and fully reversible (delete this file + its <link>
 * and the two small markup blocks to restore the original site exactly).
 * ========================================================================== */
