 * Leximoo holding page - "Ink, Paper & Signal" (ADS §10; tokens mirror packages/ui/src/tokens/tokens.css).
 * No web fonts are fetched (no third-party requests): Newsreader (ADR-0010) is used when installed, with a
 * serif fallback; the UI sans falls back to the system stack.
 *
 * Contrast (WCAG 2.2 AA): Ink #0e1a1f on Paper #f7f5f0 = 15.8:1; muted #4b5355 on Paper = 7.6:1;
 * Paper on Ink (button) = 15.8:1. Signal Vermilion appears only in the logo artwork's mark, never as text.
 * The logo is the owner's PNG artwork under /brand (see docs/brand/README.md); the ink-coloured text in it
 * sits on Paper at the same 15.8:1.
