/* ==========================================================================
   Process film — components/marketing/ProcessFilm.tsx.

   A short looping film of a site being designed in Figma, written as code
   and going live, beside three captions. Loaded per page through
   ServicePageData.extraStyles on the web-design pages, and through the
   styles list on /custom-web-design-and-development/. The section header
   uses offer.css (.ofr__eyebrow, .ofr__h2, .ofr__lead), which every one of
   those pages already loads; this sheet owns the frame and the steps.

   NAMESPACE. `pfm-`. The palette is declared here with fallbacks rather than
   inherited from .svcd-section, because /architected-websites/ and the
   custom-web-design page do not load service-devices.css and the section
   has to look the same everywhere.

   THE FRAME is the site's "ours" panel (service-devices.css, .svcd-panel:
   a lit purple panel means ours) with the mat padding of .svcd-frame,
   reproduced under this namespace for the same reason the palette is.

   ALSO HERE. The film as a hero backdrop (.pfm-hero) and the frame on its
   own beside another section's copy (.pfm__inner--head, .pfm-stack).

   MOTION CONTRACT. Everything ships finished. From-states live only behind
   html.has-motion, which motion.js adds solely under
   prefers-reduced-motion: no-preference. .is-in is set on [data-stage] by
   motion.js, with an IntersectionObserver fallback in offer.js. The video is
   decoration: under reduced motion it is hidden and the poster frame stays.
