/* KARWABAR MARKETING SITE (docs/35, D-439/D-440).
 *
 * VISUAL DIRECTION (Sami, 2026-08-27): white ground; NAVY #16345F primary;
 * SAFFRON #F1A31F accent; coral and green ONLY where they carry meaning
 * (green = completed/arrival, coral sparingly). Soft coloured circles at low
 * opacity BEHIND the content — large, few, slow, PLAIN CSS: our visitors are
 * on the same low-end Android phones and slow connections the app is built
 * for, so WebGL/canvas particles and cursor-driven effects are excluded by
 * design, not omitted (a landing page that takes fifteen seconds to render
 * has already lost them; a cursor effect does nothing on a touchscreen).
 * Reference intent (21st.dev container-scroll / gradient-orb) adapted, never
 * copied — D-190.
 *
 * NO WEBFONT, deliberately: the audience's Android devices ship Noto's
 * Arabic-script faces system-wide, and a half-megabyte font download against
 * a ~5 GB monthly data basket fails the site's own cost rule (doc 24 §8's
 * reasoning). The stack below prefers the system Naskh everywhere.
 *
 * RTL-FIRST: the documents default to lang="fa" dir="rtl"; every property
 * here is logical (start/end), so the English toggle mirrors for free.

   to any author `display` rule, and `.btn` sets one. So the site showed a
   "Download the app" button pointing at "#" — a dead control on a page about
