/*
 * App Shell — shared mobile-first layout system
 * -----------------------------------------------
 * Extracted from Home.razor so the same "app shell" look (header + tab bar,
 * hero card, quick-action grid, promo cards, service list, bottom nav)
 * can be reused on other pages.
 *
 * Usage: wrap page markup in <div class="app-shell"> ... </div> and compose
 * it from the section classes below. See SKILL.md next to this file for a
 * full guide and copy-paste examples.
