/* ==========================================================================
   The Shot List / La La Land (2016)
   Design system: "CinemaScope at magic hour"
   Deep dusk indigo, off-white type and ONE accent, Mia's yellow. Magic-hour
   pinks live only inside the drawings and the hero art, never in the UI.
   Bodoni Moda for titles (a high-contrast studio-era serif), Newsreader for
   reading, IBM Plex Mono for the slate lines under every frame. Every still
   is shown at the film's 2.55:1, cropping any letterbox and never
   stretching. One theme.
   The hero card and both demos are page.js; the drawings and the sign-off
   are art.js. Text and stills never animate on scroll. The hero opens out
   once on load; drawings draw on once (art.js); the demos move only when
   the reader asks. Everything is still under prefers-reduced-motion.
