/* ═══════════════════════════════════════════════════════════════════════════
   Rindit — the marketing site.

   One stylesheet for seven static pages. No framework and no build step, so a
   copywriter can change a sentence without installing anything — which is the
   practical difference between copy that gets improved and copy that gets
   frozen.

   **The palette is the application's**, lifted from `frontend/src/styles/
   tokens.css` rather than reinvented, so the site and the product look like one
   thing. That includes the darkened green: WhatsApp's #00a884 clears neither
   white nor dark text at 4.5:1 in a light theme, and the app fixed it. A
   marketing site that used the undarkened version would fail the contrast rule
   the product holds itself to, on the page that claims the product is careful.
