/* ============================================================
   Lumina Dental Template — Brand Override Layer
   These variables are overridden inline by build_client.py
   using values from site_data.json brand tokens.
   This file provides safe fallbacks matching the original.

   IMPORTANT: Tailwind v4 compiles utilities into @layer blocks.
   Non-layered CSS always wins over layered CSS in the cascade.
   To avoid breaking Tailwind utilities, ALL custom rules here
   are wrapped in the matching @layer blocks.
