/* Vantopia Van × Brandcore — presentation stylesheet.
   One coherent system, zero override layers.
   Surfaces: Coastal Obsidian Slate (#0B1017 / #131B26) and Warm Birch Paper (#FAF6EE / #F2EBDD).
   Brand accents drawn from Vantopia Van's official Sprinter & mountain sunset mark:
   Sunset Orange (#EA580C / #FF7838), Warm Bamboo Gold (#FBBF24), and Deep Canyon Rust (#9A2B0B).
   Every text colour below is paired with the surface it actually sits on and
   measured at WCAG AAA (7:1+ for body/small/mono text, 4.5:1+ for large display text). */
