/*
  ASDEV Design System — Components
  Framework-free component library built on asdev-tokens.css variables only.
  Namespaced with `asdev-` to avoid collisions when dropped into another app.
  No JS is required for base functionality: tabs, theme switching, toggles,
  checkboxes and the modal all work via native form controls + :has(); JS
  (preview.js) only adds ARIA syncing, focus management and toast timers.

   The shell responds to the SPACE IT IS GIVEN, not the browser viewport,
   so it behaves correctly both at the top level of an app and when
   embedded in a narrower panel (e.g. this preview's viewport simulator).
   Any ancestor that sets `container-type: inline-size` (see
   .asdev-shell-frame below) turns on this behavior; without such an
   ancestor, browsers simply skip the @container rules and the shell
   stays in its default (desktop) layout — a safe fallback. */
