   Deskmap website — "cinematic" design system (black stage / white keynote).
   Loaded by website/layout.html on every normal page, and by the home pages
   (layout: bare, `css: cine, home`) before home.css. Legacy pages
   (layout: legacy → classic/, motion/) use site.css instead; never mix them.
   Theme: :root[data-theme="light|dark"] (toggle in cine.js, localStorage
   'deskmap-theme', ?theme=), otherwise the system setting. No web fonts:
   the SF system stack. No third-party requests.

   COMPONENT INDEX (reuse these class names; page-only rules go in a page
   stylesheet loaded with front matter `css:`)

   FAQ ........... .faq > details > summary + .a > p
   Prose ......... .prose — long Markdown (h2–h4 with a.anchor, p, ul/ol,
                   tables, pre/code, blockquote, .callout, details, hr, img)
   Motion ........ .rv (reveals on scroll via cine.js; static with reduced
                   motion or without JS — html.js gates the hidden state)
