/*
 * The docs site's one stylesheet (developer docs decision, D11; docs/brand/docs-site.md). The
 * website's neutrals, ink on white and warm white, hairlines instead of shadows; gate blue in the
 * product's role: links, the current navigation entry and the focus ring, nothing else. Light and
 * dark, the first one from the system; the script stores a choice as `data-theme` on the root.
 * The build gives each font its hashed address (src/site.ts). Contrast pairs: src/contrast.test.ts.
