/**
 * assets/css/app.css
 * ------------------------------------------------------------
 * Sits ON TOP OF Tailwind (loaded via CDN in partials/_head.php).
 * Tailwind's play-CDN build cannot compile @apply, so this file is
 * plain CSS: design tokens as custom properties, plus the handful of
 * components that are awkward to build from utility classes alone
 * (modal, toast, bottom nav, skeletons). Everything else - spacing,
 * grids, text - stays as Tailwind classes directly in the HTML.
 *
 * LOAD ORDER in partials/_head.php:
 *   1. <script src="https://cdn.tailwindcss.com"></script>
 *   2. tailwind.config = { theme: { extend: { colors: { brand: {...} } } } }
 *      (kept in sync with the tokens below - see the comment at the bottom)
 *   3. <link rel="stylesheet" href="<?= asset('css/app.css') ?>">
 *
 * CONTENTS
 *   1. Design tokens (colors, radii, shadows, spacing, z-index)
 *   2. Base + accessibility (focus rings, scrollbars, reduced motion)
 *   3. Buttons + form fields
 *   4. App shell (topbar, sidebar, bottom nav)
 *   5. Card, table, empty state, skeleton loaders
 *   6. Modal + confirm dialog
 *   7. Toast (success / error / info)
 *   8. Badges, avatar
 *   9. Utilities (safe-area, hide-scrollbar, truncate-2)
