Read nspd_zoning.{max_far,max_height_m,max_floors,max_building_pct,
regulation_zone_index,regulation_source} (backend PR #1847) into the urban
scan-card, urban/buildability/potential drawers and the 3D massing КСИТ-target.
Defensive: every read is optional-chained + != null guarded → identical "—"
placeholders when fields absent, so the cockpit is unchanged until #1847 deploys,
then auto-lights-up. КСИТ density = area × max_far; пятно = area × max_building_pct
(percent 0..100, verified vs backend parser); sellable labeled estimate. 3D maxFar
= nspd_zoning.max_far ?? 3.5 (finite/>0 guarded). NspdZoning type +7 optional fields.
TS strict, no any.
