   DOUBLOON STUDIO · BASE
   Reset, layout, scene shells, skip link, focus, reduced motion.
   Uses tokens only (css/tokens.css). No color or font name here.

   PAGE CONTRACT (the same text is in the site facts file at the repo root)
   - Film player owns: .scene__stage, js/film.js, css/film.css,
     site/media/.
   - Sections own: .scene__words, js/sections.js, css/sections.css.
   - Search basics own: the search-basics block in the head of
     index.html.
   - Small pages own their own .html files.
   State hooks:
   - film.js adds class "film-on" on <html> while the film runs. It is
     never added with scripts off, under reduced motion, or with
     ?film=off in the address.
   - Each .scene gets data-state="idle", "playing" or "held", and the
     scene on the stage carries data-current.
   - Scene words are visible by default. While the film runs, only the
     current scene is seen: html.film-on .film-stage >
     .scene:not([data-current]) is hidden. That one rule lives in this
     file so both sides inherit it.
