/*
 * 806ai.ai — static page styles (F3: crawlable full-HTML pages)
 * ──────────────────────────────────────────────────────────────
 * Styles the plain-HTML story / hub / West Texas pages that Google and
 * no-JavaScript visitors get. It reuses the site's own tokens
 * (styles/tokens.css) and type stacks (styles/typography.css), the same dark
 * top bar + "806 Ai News" logo, and the article reading surface the app uses
 * (.art-h / .art-deck / .art-body / .art-why / .art-trust / .art-sources), so a
 * visitor who lands here from search sees the same site.
 *
 * Deliberately light: no app JavaScript, no animation, one stylesheet.
 * Phone-first: every piece of text is 16px or larger (the logo lockup's small
 * domain line is the one brand exception), links in the header and breadcrumbs
 * are 44px tall, and nothing is wider than the viewport — the report's table
 * scrolls inside its own box instead of the page.
