/*! ==========================================================================
 * Carrier Wireless — app.css
 * Hand-written design system. No build step, no CDN, no Tailwind runtime.
 *
 * WHY hand-written: the deployment target forbids a CDN <script> (CSP) and the
 * host has no Node toolchain, so the stylesheet has to be shippable as-is.
 * Everything below is one file so WhiteNoise fingerprints a single asset and
 * the storefront paints without a second round trip.
 *
 * Layer order (single file, plain cascade — read top to bottom):
 *   1. Tokens          — design tokens from INTERFACE-CONTRACT.md §5
 *   2. Dark tokens     — the ONLY thing dark mode redefines
 *   3. Reset + base    — element defaults, typography scale
 *   4. Layout          — container, section, stack, grids
 *   5. Components      — header, nav, cards, buttons, forms, tables, panels
 *   6. Page modules    — home, catalog, cart, checkout, delivery, dashboard
 *   7. Utilities       — spacing/visibility helpers used sparingly in markup
 *   8. Media           — reduced motion, forced colors, print
 *
 * Markup contract expected by app.js / cart.js (see static/js/*.js):
 *   header:   <header class="site-header" data-header>
 *               <button class="menu-toggle" data-menu-toggle
 *                       aria-expanded="false" aria-controls="site-menu">
 *               <nav id="site-menu" class="site-nav" data-menu>
 *               <a class="cart-link"><span class="cart-badge"
 *                       data-cart-count data-count="0">
 *   accordion:<div class="accordion" data-accordion>
 *               <h3><button class="accordion-trigger" aria-expanded="false"
 *                       aria-controls="p1" data-accordion-trigger></button></h3>
 *               <div id="p1" class="accordion-panel" hidden>
 *   copy:     <button class="copy-btn" data-copy data-copy-target="#lpa">
