/* The Bay Architects × Brandcore — presentation stylesheet.
   One coherent system, zero override layers.
   Surfaces: Warm Architectural Linen (#F4F0E6) and Deep Architectural Slate (#121820).
   Brand accents drawn from East Bay landmark masonry, redwood timber & cartographic ink:
   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). */
