/*
 * Clawgnition landing page — "Nocturne".
 *
 * A dark, quiet stage for one phone. The landing re-points the shared tokens
 * from site.css at night values (so the shared header, buttons and footer
 * follow), then layers its own choreography on top: an orbit of the eight app
 * hues around a live device, a convergence diagram, an on-device chat, and a
 * sealer that turns a note into ciphertext.
 *
 * Every animation here is progressive: the page reads fully without
 * /js/landing.js, and `prefers-reduced-motion` (site.css) collapses the motion
 * to its final state. Hidden-until-revealed states are scoped under `.js` so a
 * script failure can never hide content.
