/* galley — site surface.
 *
 * The page this replaces was a cream document: an 880px column of monospace
 * prose with the one thing worth seeing — an actual rendered release video —
 * pushed a screenful and a half below the fold, behind three paragraphs
 * describing it. For a tool whose entire output is a moving picture, that is
 * the wrong order.
 *
 * This is a darkroom. The video is the first object on the page, lit against
 * a dark ground the way a screen actually is, with the numbers it renders
 * repeated beside it as an instrument readout. Everything else is a band
 * under it.
 *
 * Colour rule: every colour is declared once, in :root, and composed with
 * var() everywhere else.

/* ============================================================ 1. FACES ==== */
/* Three roles in three faces. The video itself is set in JetBrains Mono, so
   the site keeps mono for every number, path and command — the things the
   product renders. Display and prose get faces of their own so the page has
   a voice distinct from its own output. All three are OFL 1.1, self-hosted
   beside their licences; this page makes no third-party requests. */
