   Compare Matrix (closing.jsx CompareMatrix) — mobile rendering.

   The matrix is a 5-column axis-by-tool grid on desktop. The global
   mobile-collapse rule above collapses it to 1 column at ≤768px, which
   is the right default. Two tweaks make the stacked version readable:
   1. Hide the column-header row — it's just a list of useless labels
      once columns are stacked.
   2. Prefix each value cell with its tool name via data-label/::before,
      so readers can tell which tool a given value belongs to without
      the column header. ARIA cell suppresses the prefix because its
      higher-opacity styling already signals it as the "us" column.
