/* =============================================================================
   Feedback modal + header button

   Loads after 80-command-palette (shares its modal chrome conventions) and
   before 90-symbol-search, neither of which it touches. Everything here is
   scoped to `.sfa-feedback-*`, and every colour comes from a token, so the
   light and CVD themes flip for free. Only two things are hardcoded enough to
   need a `body.theme-light` override at the bottom: the drop shadow and
   Bootstrap's close glyph, which is an image rather than a colour.

   The form is longer than the rest of this UI is dense, on purpose: it is the
   one screen aimed at somebody who has never seen the app before.
