/* =============================================================
   App dialog — the themed replacement for alert(), confirm() and
   prompt(). Built by app/components/dialog.js on a native <dialog>
   opened with showModal(), so the browser supplies the top layer,
   the focus trap and Esc; this file only supplies the look.

   Colours come from the --app-* tokens in app/themes/themes.css,
   so light, dark and calm all drive it. The backdrop blur is the
   shared dialog::backdrop rule in modals.css.
