/* Landing page (AI-448): public marketing + showcase home at "/".
   Token-driven — inherits palette + theme from tokens.css (loaded first) and
   palette.js (data-palette / data-theme on <html>, dusk from 19:00, ?palette=
   / ?theme= overrides). No hardcoded palette hex: colours come from the
   semantic variables so the landing tracks the four palettes and light/dusk.
   The one allowed literal is white button text (#FFFDF7). Icons are CSS
   shapes; hero art is the only image asset. */
