   Beach Cities Aviation — flight school site
   Aesthetic: SpaceX-style — near-black, huge condensed type, full-bleed
   imagery, minimal chrome. Brand navy #1E3A5F (see brand/brand.yaml).
   Image slots: .media-slot[data-shot] renders a labeled placeholder until
   the real photo/video drops in — see the shot list in README.md.
   Design-review pass applied 2026-07-06 (mobile header/menu, scrims, a11y).
