   Hero — scroll-driven zoom-through-text, then the cartridge photo + logo
   -----------------------------------------------------------------------
   .hero-scroller is an oversized (220vh) block; .hero-pin sticks to the
   viewport for the ride. assets/js/home.js reads how far the page has
   scrolled through that extra height (0 -> 1 "progress") and drives three
   things directly off it, no fixed timers:
     - .hero-intro-text scales up (a zoom "through" the letters)
     - .hero-bg / .hero-overlay crossfade in as the intro fades out
     - .hero-content (logo, subtitle, CTAs) fades/rises in last
   Scrolling back up reverses all of it. See home.js for the exact
   progress thresholds. Every element's *default* (pre-JS) state below is
   also the correct prefers-reduced-motion end state, so reduced-motion
   users and no-JS visitors both just see the final hero immediately.
