/* v3 2026-06-22 — top was 60px to sit below the page .header (which is
   sticky at top:0, height 60px). That math only works if sticky is computed
   against the viewport. But .table-container has overflow-x: auto, and per
   CSS spec setting one overflow axis to non-visible computes the other to
   auto — making .table-container the scroll container. Sticky <th> then
   computes 'top: 60px' as "60px below the table-container's top", which
   pushes the header DOWN onto the first tbody row, hiding it.
   Fix: top: 0. The header sits at the top of its scroll container (the
   table itself), which is where it naturally renders anyway. No viewport-
   relative sticky behaviour, but the page header is already sticky at top:0
   and 60px tall, so the column header scrolls under it on long pages —
   which is the conventional pattern on this app's other list pages. */
