/*
 * zragellc.com — the Zrage LLC company site.
 *
 * One stylesheet, four pages, no build step and no third-party requests. The
 * fonts are self-hosted for that reason: an Amazon reviewer reads this site,
 * the privacy policy claims "no cookies, no analytics, no third-party
 * requests", and a webfont CDN would quietly make that claim false.
 *
 * The look is a printed spec sheet — warm paper, ink, one sienna accent,
 * hairline rules, numbered sections, and a monospace rail for metadata.
