/*
 * Shared by privacy.html and terms.html.
 *
 * An external file rather than a <style> block in each, because these two pages
 * are identical furniture around different words, and the failure mode of
 * duplicating it is the one you cannot see: two legal pages that quietly stop
 * matching each other and the landing page.
 *
 * `style-src 'self'` in _headers already allows it. The tokens are the same
 * ones index.html carries; they are repeated rather than shared because that
 * page has no build step to inline them from, and a second stylesheet request
 * on the landing page is a worse trade than these thirty duplicated lines.
 *
 * These pages are deliberately NOT translated. They were written without a
 * lawyer (the operator's decision, 2026-09-24), and an English version would be
 * a second unreviewed legal text saying something subtly different from the
 * first — which is worse than having none.
