Videos: font swap from JL's list + lightbox QoL fixes

Fonts (display/heading only — body untouched):
- Cringe Pit: Bebas Neue → Protest Revolution
- Renegade: Bebas Neue → Ribeye Marrow, Barlow Condensed → Faculty Glyphic (headings), Rambla (body)
- Nomad Soul: Bebas Neue → Trade Winds, Rye → Babylonica
- Hub: Bebas Neue → Workbench

Lightbox fixes (3 collection pages):
- window.onload → DOMContentLoaded (fires before iframes load, fixes slow mobile)
- lightbox-content: max-height 90vh + overflow-y auto (fixes off-screen on small viewports)
