/* ---------- Responsive data tables: card layout below 768px ----------
   Row-dense tables (events/tickets/members/refund) are unusable on a phone
   as a shrunk table — cells get too narrow to read or tap. Below 768px each
   <tr> becomes a card and each <td> becomes a labeled row (label from the
   td's own data-label attribute, so the row template doesn't need to
   duplicate the <th> text). Table markup/semantics are unchanged above
   768px; this only kicks in at the breakpoint where a real table stops
   being usable with a thumb. */
