Mobile responsive pass

- PixelLogo scales to viewport via a responsive hook so FACERE no
  longer overflows narrow screens.
- styles.css mobile breakpoints (760px / 480px / short-landscape)
  unwrap headlines/body copy, compact the HUD, allow the install
  command to wrap on tiny phones, and re-aim the bg pan origins so
  the meaningful slice of each landscape image stays in frame.
- Shorten scroll-track to 480vh on phones — the GSAP timeline still
  scrubs by progress so the choreography is preserved, just less
  exhausting to swipe through.
- Bump cache-busting query string on css/jsx.
