/* QuantumCat marketing site — "paper & glass".
   Two kinds of surface alternate down every page: warm PAPER sections carry
   the argument, and black CINEMA sections carry the product — the terminal
   bleeds edge to edge with no window chrome, because it is dark by nature and
   is the art. `.cinema` re-scopes every token, so the same components
   (buttons, cells, frames, forms) render correctly on either surface, and
   `[data-theme=dark]` turns paper into charcoal while cinema stays black.
   Type: Instrument Sans (UI), Instrument Serif italic (the display word),
   JetBrains Mono (every number, label and tool name). All self-hosted. */
