hero: make the portals real recesses and land the facade on Z 0

The portal detail shot failed for a modelling reason, not a camera reason: the
doors were 0.1 m panels on a solid plinth, so they read as shading. The plinth is
now four piers plus a lintel band, with a 1.2 m reveal, stone jambs and lintels
standing 0.10 m proud and three mullions per opening. review-06 frames them from
8 m at eye height.

Two defects fixed while doing it: the jamb boxes hung 0.15 m below the pavement,
so the facade imported with min Z -15 cm; and a rebuild run against a read-only
.blend silently skipped the save, which is why screenshots kept showing the old
geometry.
