 * Clawgnition public site — shared design system ("Document of record").
 *
 * A cool archival-datasheet aesthetic: near-black spruce ink on cool paper,
 * one deep-green accent (harmonizing with the claw mark), heavy label rules.
 * Editorial serif headlines (Newsreader), a precise monospace for every fact
 * and number (Spline Sans Mono), a clean grotesque body (Hanken Grotesk).
 *
 * Shared by the landing page, /docs/*, and the legal pages. Everything here is
 * page-agnostic; landing-specific rules live in landing.css.
