/* ── Two-row rail (6+ lessons) ──────────────────────────────────
   Up to 5 lessons the rail is one row and the active tab merges into the card
   below. From 6 it becomes a balanced grid over two rows and the tabs detach
   into outlined pills: a tab in the upper row cannot merge into a card it is
   not touching, so the merge is dropped rather than half-applied.

   Column counts are quantity queries — later rules override earlier ones, so
   9 tabs matches the 6, 7 and 9 rules and ends on 5 columns:
     6 → 3 cols (3+3)      7,8 → 4 cols (4+4)
     9,10 → 5 cols (5+4)   11,12 → 6 cols (6+5)

   Scoped to min-width 1025px on purpose: :has() here scores (0,3,0) and would
   otherwise outrank the (0,2,0) tablet and phone rules further down the file,
   forcing five columns onto a 375px screen.
