feat: hero facade blockout for 6840 Hollywood Blvd

Tools/hero_facade_build.py builds the north elevation parametrically and writes
a JSON report naming the evidence behind every part: the 25.75 m frontage and
14.5 m height are measured, the 4.96 m column bay comes from the sibling notes
and matches that frontage, the three portal flights follow the photographs (five
risers, overturning the inherited eight-step, 12 m wide claim), and the rest is
labelled assumption.

Tools/ue_hero_facade_import.py imports it with the ue_metric_v1 preset
(2604 x 1257 x 1450 cm, 1892 tris, 4 materials) and places it on the measured
building line of /Game/Hollywood/DemoMap.

Two new review shots at review-04 and review-05, both pending approval. Camera
placement cost four renders: the first two sat inside the facade body, and the
frontage faces Unreal -Y, so a camera has to stand at Y < -1450 cm, not north of
the building line in project terms.
