/* YazSes landing page (overrides/home.html).
 *
 * Every selector is scoped under .yz-landing / .yzl-*, or gated on
 * body:has(.yz-landing), so nothing here reaches any other page.
 *
 * Colour system. The brand violet (#5e35b1 / #7c4dff) is the site's existing
 * primary. Cyan is "signal" (audio, live data), mint is the tray's recording
 * green, and the amber #eb6834 is the same "designed, not yet built" orange the
 * architecture figures already use (extra.css, .yz-fig --yz-plan), so the two
 * surfaces mean the same thing by the same colour. Dark sections are fixed-dark
 * in both schemes; the rest follow Material's light/slate variables.
 *
 * Motion respects prefers-reduced-motion: every animation is disabled and every
 * reveal is shown in its final state.
