Typography + pill explosion + video loop fix

- Serif fonts (Playfair Display + Noto Serif SC) for narrative text
- Captions: 700 weight, larger size, glow text-shadow for visibility
- Empire title: larger (6vw), serif
- Break-free: italic serif with breathing glow
- Pill split: 2.5x wider opening, 30 intensity inner glow, white screen flash
- Video loop: fade out in last 1s to avoid jarring restart
