   CATALOG GRID — ROW TRACK SIZING FIX
   Chrome computes near-zero intrinsic height for flex-column cards that have
   overflow:hidden, so auto grid row tracks collapse to ~50px and card content
   is entirely clipped. Fix: row 1 (progress dashboard) stays at natural height
   via grid-template-rows:auto. The 220px floor is applied directly to
   .subject-card (below) rather than to grid-auto-rows, so full-width rows
   that share the implicit row track — the "View Career Path" banner and the
   track-group headers — aren't forced to the same height and stretched into
   an awkward empty gap.
