Wave-5 refinement round 5 (owner): glyph-shaped SVG marks, vertically centered

- Option rows: items-start → items-center — the icon span's top-misalign
  came from the row alignment; now marks center across the row.
- The literal ✓/✗ look (owner preference over the round-3 lucide set)
  re-rendered as hand-rolled SVG with thick rounded strokes (strokeWidth
  3, round caps/joins) — the glyph shape, as a true vector, sized like
  the row text. Test pins updated to data-mark=check|x.
