     Palette: Deep Forest (#0C1511) dark theme with aged-gold chrome
     and sap-green highlights. Variable names retain their historical
     "navy-" / "sage-" / "ink-" labels to avoid touching 900+ downstream
     rules; the *values* have moved. The theme is now dark, so:
       - "ink-" tokens are LIGHT (text-on-dark)
       - "surface-raised" is LIGHTER than "surface-base" (cards lift)
       - "surface-sunken" is DARKER than "surface-base" (wells recede)
       - "navy-800" is the primary ACCENT (aged gold) that drives chrome
       - "sage-600" is the secondary ACCENT (sap green) for links
