Font refactor: replace generic display fonts across Videos + Writings

Renegade Storyteller:
- Ribeye Marrow → Amarante (Art Nouveau, cleaner mobile rendering)
- h1 floor reduced 4rem → 3rem
- h1::before letter-spacing tightened on mobile (was overflowing narrow screens)

Writings (11 files via script):
- Bebas Neue → Fredericka the Great (4 files)
- Anton → Rubik Glitch (2 files)
- Cinzel / Cinzel Decorative → Glass Antiqua (5 files)
