/* ═══════════════════════════════════════════════════════════════════════════
   KennelCore site layer.

   organic.css is the design system and the source of truth for the look —
   colors, type, radii, shadows and the component classes. This file only adds
   what a real multi-page site needs on top of it: page layout, the responsive
   behaviour, and the handful of page-specific patterns. Everything here takes
   its values from the system's tokens; no raw hexes, fonts or spacing.
