/* Markdown Table Generator & Editor — content styles.
   Prefix: --mdt-  /  .mdt-

   Reference point: a small spreadsheet — an editable grid of real <input>
   cells with inline per-column alignment controls and row/column remove
   buttons, not a form with separate "add field" rows. Tenth distinct
   developer-cluster layout this build loop: an actual editable grid, not
   a table of read-only results.
