   Concierge Pilot — Shared Floor Designer Engine CSS
   Structural / layout styles. Colors, fonts, accents come from tenant skin.
   --------------------------------------------------------------------------
   Each tenant's index.html sets these CSS variables in :root, then this
   stylesheet renders the universal Floor Designer UI in their brand.

   Required CSS variables (tenant supplies):
     --bg, --surface, --rule, --ink, --ink-dim, --ink-faint
     --accent, --accent-deep, --accent-glow, --accent-soft
     --brand-heading-font, --brand-heading-style, --brand-mono-font
