feat: hero batch 3 — pedestrian footbridge + viaduct station platforms

- footbridge.glb: 18m truss footbridge over the central avenue one block south of the rail line — X-pattern teal trusses, mesh railings, real stair flights at both ends. Deck and stairs are WALKABLE (box deck collider + invisible ramp colliders over the stair visuals): a third elevated crossing route between the viaduct and the plaza, and a new grapple anchor over the avenue - platform.glb: station platform strips on the viaduct deck flanking the crossing — canopy on posts, benches, line signs; dresses the deck route players actually run - Fixed a parse error from an undefined color constant caught by the capture loop (blank render -> error -> fix -> verified) Movement 11/11, smoke 0 failures; full-city aerial verified.
