// Miss #52 (2026-07-30): the municipalities list hydrated ~125 idle Drawer
// roots (25 rows × 5 sheet controls) and prod tripped React #130 — CSS
// `display:none` does not remove hydration cost. The fix pattern is ONE
// shared Drawer per list surface via `CampaignListSheetProvider`, with cell
// bodies portaled into it. The provider reached the municípios mobile cards
// and this pass (2026-07-31) the three chip-relation lists (lideranças,
// dobradinhas, assessores) — this guard keeps the next chip-cell table from
// mounting sheet overlays providerless.
