/* =============================================================================
   styles.css - forest dark theme.
   Design tokens, layout, components and motion for the whole page.

   Ground is a deep forest stack (forest / pine / moss panels) with bone type,
   ONE accent (amber) and ONE signal colour (terracotta) reserved for stale /
   updates / DENIED states. Measured WCAG ratios are noted beside each token.
   Every body-text pair clears 4.5:1 and every border or diagram stroke that
   carries meaning clears the 3:1 UI floor against the deepest ground.

   The page is theme-locked: dark everywhere, no section inverts.
