/* Nelzn LLC — public site. Single stylesheet, no build tooling, no external fonts or CDNs.
 *
 * Two hard rules govern this file, both enforced by scripts/check-site.mjs:
 *   1. No url() and no @import that reaches another host. No webfonts, no icon sets, no images.
 *      Every glyph on the site is either an inline SVG in the page or drawn here in CSS.
 *   2. The site ships zero JavaScript, so anything interactive is CSS: <details> disclosures,
 *      :hover / :focus-visible, and scroll-driven animation. Nothing may DEPEND on that support —
 *      the reveal animation is wrapped in @supports so content is never left invisible.
 *
 * Typefaces are system stacks for the same reason a webfont would be a remote request. Display is
 * ui-rounded (SF Pro Rounded on Apple platforms) falling back to system-ui; the fallback is a clean
 * grotesk, so the page degrades in weight and personality, never in legibility.
