/* ─────────────────── MOBILE MODULES & LESSONS ───────────────────
   The default (≥601px) layout is a zigzag: a big circular number on
   one side and the white .pm-mod-info card on the other, with the
   number badge and the lessons-panel taking up roughly half the row
   each. On mobile that flex-row pattern collapses every text node into
   a column ~150px wide — lesson titles get clipped to "Modal Improvis…"
   and the action pills wrap to two side-by-side buttons that no longer
   align with the card padding.

   We rebuild the layout for ≤600px:
   - Wrapper goes column, killing the zigzag (flex-direction reset).
   - Number badge becomes a smaller chip pinned to the top-left of the
     info card so the title can use the FULL row width.
   - Info card padding tightens (16px 14px) so the lesson cards inside
     have room to breathe and the title can render across 2-3 lines.
   - .pm-mod-actions stacks vertically, left-aligned, with each button
     left-aligned (NOT full-width — the user explicitly asked for them
     vertically aligned to the left). Max-width:fit-content keeps them
     compact and readable instead of stretched.
   - Lesson cards inside the panel get a slimmer left padding so the
     number bubble + title + meta line up cleanly. */
