/**
 * theme.css — Main landing page styles for stratusclean.polsia.app
 * Owns: landing page layout and brand tokens
 * Does NOT own: dashboard (dashboard.css), vertical pages (vertical.css)
 *
 * Brand tokens (confirmed hex values):
 *   Hero Green    #43B02A  (dominant: hero, CTA, primary)
 *   Charcoal Grey #333F48  (authority sections, body text)
 *   Cloud Grey    #D0D3D4  (section backgrounds, muted)
 *   Light Gold    #BD9A51  (RGB 189,154,81 — proof badges, accents)
 *   NOTE: Style guide PDF listed RGB 140,201,115 for Light Gold — those are
 *   green values, not gold. Correct derivation is from #BD9A51 (189,154,81).
 *
 * Typography:
 *   Headlines: "Open Sans" Bold (Town 10 not available in Google Fonts)
 *   Body: "Open Sans" Regular
 *   NO blue anywhere (links use charcoal or green-on-hover)
