/* ==========================================================================
   Blocks Modal Component
   ==========================================================================

   Scrolling strategy (cross-browser, including Safari):

   Avoids position:sticky (Safari bleed-through bug). Instead, the table
   uses display overrides to structurally separate the header from scroll:

     <table>  → display: flex  (column)
     <thead>  → display: block (flex-shrink: 0, never scrolls)
     <tbody>  → display: block (overflow-y: auto, sole scroll container)
     <tr>     → display: table (table-layout: fixed, keeps columns aligned)
