/* ── Older-browser fallback ───────────────────────────────────────────────
   oklch() colors only work in Chrome 111+. In older Chrome var(--accent) is
   invalid, so .btn--primary (white text on var(--accent)) — incl. "Sign in" /
   "Start free" — renders invisibly. Browsers without oklch get these hex
   equivalents; modern ones keep oklch. Last so it wins the cascade. */
