/* The style of the static network pages, once.
 *
 * These pages are plain HTML: no Angular, no framework, no third-party request
 * - they exist to be read by crawlers that do not run a framework, and by
 * people on a slow connection. What they are NOT allowed to be is a second
 * design: the header, the buttons and the footer below are the Angular site's
 * own, transcribed. The tokens come from tailwind.config.js and styles.scss,
 * so a page here and a page there look like the same product.
 *
 * Rewritten 2026-09-17: the first version invented its own violet (#8b5cf6
 * instead of the site's #7c3aed), set its headings in Outfit where the site
 * sets everything in Inter, gave the header a wordmark with no logo, and left
 * the two calls to action as underlined links in a paragraph.
 *
 * networks/robinhood-chain/index.html keeps its own inline copy: it is the
 * Locker product's page, not the wallet's, and it is live and proven.
