/* ==========================================================================
   ABC Construction — public site
   --------------------------------------------------------------------------
   Design intent (README sections 2 and 3): read as a working contractor's
   site, not a template. The visual language is borrowed from site signage and
   engineering drawings — hard 2px edges, heavy black rules, condensed
   uppercase display type, visible grid structure, hazard stripes used as an
   accent rather than decoration.

   Deliberately avoided: soft floating cards, pastel gradients, glassmorphism,
   centred hero + three-icon-row, and decorative motion. Those read as generic.

   COLOUR CONTRACT — the single most important rule in this file:
   construction yellow on white is ~1.7:1 and fails WCAG AA outright. Yellow is
   therefore only ever a BACKGROUND carrying black text (~13:1), which is also
   how real safety signage works. Yellow is never used for text or for a thin
   line that must be read.
