/*
 * Tenet — the marketing site.
 *
 * The palette is the app's own (app/src/app/globals.css, "Glacier"):
 * layered near-blacks, white ink, and colour only where the app has it —
 * the red playhead and the muted port colours that tell wires apart on the
 * canvas. Everything coloured on this page is either footage or one of
 * those. Type is Inter Tight throughout — the app's own Inter, set tight
 * for titles. Mono is for timecode only, as in the app.
