The multi-box gate is authoritative, but adapters still need to FETCH the
right data — otherwise a box crossing a state line never pulls the cross-
state side. Feed each adapter's fetch scope (fires envelope, nws area=states,
hydro bBox, etc.) from the enclosing bbox of config.coverage.areas (falling
back to legacy coverage.bbox). The Shapely gate still narrows to the exact
areas; the enclosing box just ensures cross-state / multi-area data is pulled.
