/*
 * WarungTetangga.com — global stylesheet
 *
 * Retrofit pass: applies a cohesive visual design to the whole app via plain
 * semantic-element selectors, with (almost) no markup changes required in
 * public/index.php. Every page already flows through
 * App\Support\Layout::render(), so linking this one file (see Layout.php)
 * styles every route: customer, merchant and admin.
 *
 * Brand: warm, approachable, trustworthy "neighborhood marketplace" look.
 * Palette anchored on the existing PWA brand green from manifest.json /
 * Layout.php's <meta name="theme-color"> (#2e7d32) — no new colors invented.
 *
 * Scope: mobile-first PWA. No CSS framework, no build step, no CDN — a
 * single hand-written file, loaded statically from /assets/app.css.
 * Dark mode intentionally out of scope for this pass.
