 * Token discipline: every color, font-family, size, space, radius,
 * border, and motion constant here resolves through var() from
 * tokens.css. No literals — the token-isolation test enforces the
 * color and font rules.
 *
 * Design language: the "stack" redesign, after Paradigm and
 * Hummingbird — a warm paper ground, near-black ink, an editorial
 * serif for display, mono for every number and key hint, thin line
 * art (the isometric stack), numbered sections, and one vermilion
 * accent spent on kickers, hover sweeps, focus rings, and the lifted
 * block. Motion: one-shot intro reveals, a slow turning stack, a
 * marquee of names, scroll reveals, and a company page that slides in
 * and staggers its facts. Every animation switches off under
 * prefers-reduced-motion (last block in this file).
