/*
 * [Summary]: Main stylesheet cho mall_shopping — layout, header, footer + design tokens.
 * [Flow]:
 *   1. CSS variables — palette TransViet + semantic tokens (text/border/surface) + spacing/radius.
 *   2. Reset + base typography (Inter font, body color, link).
 *   3. Layout primitives — .container, .site (sticky-footer flex column).
 *   4. .announcement bar — yellow strip trên cùng.
 *   5. .site-header — sticky top, logo + nav (dropdown hover) + search + actions + hamburger mobile.
 *   6. .site-footer — blue dark, 4 cột top section + bottom strip copyright.
 *   7. Responsive: ≥1024 desktop full · 768–1023 tablet · <768 mobile (nav→hamburger).
 * [Notes]:
 *   - Palette do user cung cấp; mọi color reference qua CSS var, không hardcode HEX trong block.
 *   - Mobile nav toggle qua attribute `hidden`, script trong base.html.
