/* --- Modal ---
   Bug note: the old version used the `hidden` attribute for visibility,
   but this rule's own `display: flex` has equal specificity to the
   browser's built-in `[hidden] { display: none }` rule, and author CSS
   always wins that tie — so the modal never actually hid. Fixed by
   keeping `[hidden]` as the hard "not in the DOM flow" switch and using
   a separate `.open` class purely to drive the fade/scale transition. */
