First regional surface in /campanha: a sortable 27-TI overview table on the
Início staff dashboard, next to the municipal map. Per-TI aggregates only
(sums and ratios of aggregates — MAUP safeguard); Metropolitano decomposed
into Salvador (19 zones) vs. demais RMS. Loader is server-only with
overrideAccess:true (regional context, not management; TI-level exposure
only); pure rollup stays client-safe for the sortable table. First slice of
E12, which extends with capture/LQ/meta coverage.
