/* Kalku marketing site.
 *
 * Same tokens as docs/privacy-policy.html and docs/terms-and-conditions.html —
 * the app's dark-only palette, Space Grotesk, the oklch accent family — so the
 * landing page and the two legal pages read as one site. Nothing here shares
 * code with composeApp's theme; the values are transcribed by hand, as they are
 * on those two pages.
 *
 * Written with logical properties throughout (inline-start/end, margin-inline)
 * so the Arabic page mirrors from `dir="rtl"` alone, with no per-locale CSS.
