  /* Below this width a multi-column table has no room to breathe — 3-5
     columns squeezed into ~300px forces every cell to wrap, so values like
     a phone number or "Spouse and emergency proxy" become unreadable even
     inside a scroll container. Re-lay each row as a small vertical card of
     label/value pairs instead (a standard responsive-table technique) —
     the label comes from each <td>'s data-label attribute, which mirrors
     its column header (translated on the public page, same as the header
     itself). No horizontal scrolling needed anymore at this width. */
