/* «الإبلاغ عن عطل فني» — the floating button and its dialog.
 *
 * Deliberately namespaced `br-` and NOT built on `.modal`: modal-motion.js
 * holds `display` non-none for ~180ms on close, and this dialog is opened and
 * closed from a button that sits above every page's own layers. It carries its
 * own open/close transition instead.
 *
 * Colours come from the page's variables (--white, --text-primary, …) so a
 * teacher-themed dashboard recolours it for free; the fallbacks are what keep
 * it readable on a page that never loaded base.css.
