Map 1: rebuild Hollywood as the El Capitan landmark

Replace the generic boulevard facade with a stylized 6840 Hollywood Blvd block: six Ionic columns, eight stone steps, Masonic frieze/medallions, event banners, side doors, El Capitan Theatre and retail neighbours, Ovation Hollywood arcade, Walk of Fame and four-lane street markings.

Add the Day and Night Hollywood venue-menu rows. Night uses a phase-time offset so a full-length shift stays in LATE while the clock starts at zero; late routine traffic keeps the street populated and the offset round-trips through checkpoint restore.

Retune local-light falloff to linear attenuation, add a cool north sky fill, and use the smooth limestone facade texture. Refresh the staged gallery and map references; add geometry-budget, menu, night-offset and late-traffic tests.
