/*
  AI Frontdesk website.
  Layout: left-aligned editorial column with a 12-column grid; each page opens with a plain statement,
  then alternates full-bleed bands (canvas / surface) so sections read as distinct rooms, not cards.
  Type: Fraunces for headings (warm, residential, used sparingly), Public Sans for reading (shared with
  the staff app), IBM Plex Mono for the things this product actually prints: reference numbers, phone
  numbers, timestamps and SMS text.
