/* Ginza CRM. The look follows the Copilot CRM screens (Guestbook,
   Reservations): the same token names and values as branding.py's derived
   default palette (light, with dark when the phone or computer is in dark
   mode), and the same components: the 52px bar, the big top tabs, .hbtn and
   .hbtn-gold buttons, section bands, pills. Colours come only from tokens,
   so a later brand switch changes this file's :root and nothing else. */
