/*
 * components/search-overlay.css
 *
 * What:  Styles for the Zomato-style search overlay. Two layouts:
 *          • Mobile (<768)  → full-screen panel covering the page
 *          • Desktop (≥768) → centred floating card with backdrop
 *
 *        Visual states inside the panel:
 *          • Empty   — recent-searches chip row + categories grid
 *          • Typing  — vertical list of result rows
 *          • No-match — italic "nothing matches" line
 *
 * Why:   Single source of styles for the overlay so the partial markup
 *        stays content-only.
 * Used:  Loaded by views/_layout.ejs. Markup mount lives in
 *        views/partials/search-overlay.ejs.
