/* ---------------------------------------------------------------------------
   Family Registration UI

   Two audiences, one stylesheet:
   - Families, on a phone, once, possibly in a hurry. Big targets, few words,
     nothing to type.
   - Panitia, on a laptop, for an hour. Dense tables, small controls.

   Mobile-first. No horizontal scroll at 360px; wide tables scroll inside their
   own container rather than pushing the page sideways.
