   16. TABLE -> CARD REFLOW AT 720px
   The 720px breakpoint is the Raven convention for table-to-card transitions.

   Usage: mark <table> cells with data-label="Col header".
   The CSS shows those labels as ::before pseudo-headings in card layout.

   To activate for a specific table, add the class .reflow-720 to the <table>
   element. (Or scope per table-id as driver-admin.html does.)

   Example HTML:
     <table class="reflow-720">
       <thead><tr><th>Name</th><th>Team</th><th>Actions</th></tr></thead>
       <tbody>
         <tr>
           <td data-label="Name">Jane</td>
           <td data-label="Team">Alpha</td>
           <td class="cell-actions-mob">...buttons...</td>
         </tr>
       </tbody>
