File: gallery-phase14-1.css
Purpose: Phase 14.1 responsive campus selector and album lightbox refinements.

Maintenance notes:
- This file intentionally loads after the legacy gallery CSS files.
- Mobile campus selector rules override older horizontal-scroll behavior.
- Lightbox rules are additive and preserve the existing visual language.
