/* Student → owner message form, and the modal shell it opens in.
   Pages provide the common colour variables (--accent, --ink, --line, --card,

   /requests card, and inside the modal on every other top-level page. Both use
   the same markup, so everything here is scoped to .msg-form and stays neutral
   about the surrounding card. */
