/* Gomi Sensei landing page.
 *
 * Ported from the Claude Design prototype "Gomi Landing.dc.html", which is
 * written as one tree of inline styles. Everything here is that design, moved
 * into classes so the page can also survive a phone, a keyboard and a reader
 * who has asked their OS for less motion.
 *
 * Palette is the app's own "blue-hour" theme (see ../src/theme.ts). The page is
 * two-sided: deep navy sections with white type, and a pale blue section with
 * navy type. Card faces flip between the two, so colour tokens come in pairs.
