/* ==========================================================================
   Custom component layer — loaded AFTER the Tailwind CDN script on every
   page. Tailwind itself (https://cdn.tailwindcss.com, no Node/npm/build
   step) now generates every utility class (flex, gap-4, text-sm, bg-white,
   rounded-lg, border, spacing, etc.) directly from class="..." usage in the
   HTML. This file only defines the small set of reusable named components
   Tailwind doesn't provide out of the box: buttons, badges, modals, the
   sidebar/topbar shell, tabs, toasts. Dark mode for these follows the same
   [data-theme="dark"] attribute the rest of the app already uses (see
   assets/js/theme.js), configured as Tailwind's dark-mode selector too so
   `dark:` utility variants also work if used directly in markup.
