 * The app's design tokens, hand-written rather than generated. The app needs
 * Tailwind because it has a thousand components; a marketing site has nine
 * sections, and shipping a utility framework to render them would cost more
 * bytes than the whole page.
 *
 * The tokens themselves are copied from frontend/src/index.css, so the two
 * surfaces are the same product. Brand indigo is #4F46E5 — the darker one that
 * carries white text at 6.29:1, not the #6366F1 the brand is nominally built
 * on and which fails contrast on a button.
