/* Session 09 — real bug found live: #modal-shell's own ".overlay" (shared
   class with #drawer-shell/#notifications-shell's backdrop, z-index 70)
   establishes its own stacking context, so ".modal" being a *child* of it
   never actually competed against ".drawer" (z-index 71) the way the flat
   numbers suggest — the drawer's own stacking context (71 > 70) painted
   (and intercepted clicks) OVER the modal whenever both were open at once.
   This is a real, reachable case, not just a test artifact: the sync-
   conflict modal (SPEC.md §5.2) deliberately opens while the edit drawer
   stays visible behind it, so "Keep ours"/"Keep theirs" were unclickable
   the moment a real conflict fired with the edit form open — caught live by
   this session's tests/e2e/test_smoke.py conflict-flow test, a scenario no
   prior HTMX-era test ever drove with a real click. Scoped to #modal-shell
   only (not a blanket ".overlay" bump) so the drawer's own overlay-vs-panel
   relationship, and notifications' identical "drawer" class, stay
