/* ══════════════════════════════════════════════════════════════════════
   CARD-PAGE — shared structure for the business-card landing pair (S466).
   The card is a widget of the landing page: both /receptionist-l1.html
   (ARAYA OS storefront, card FRONT) and /builder-revolution.html (BR join
   page, card BACK) are Desktop/1_COMMAND/BR_BRAND/FLIP_PAIR_v6.html scaled
   up. This file owns the shared skeleton; each page supplies its palette
   by defining the alias vars below (sourced from components/araya-brand.css
   tokens — never hardcode hex on a page):

     --bg --surface --surface-hi --line   base + surfaces
     --trim                               the ~10% trim color (rule, category)
     --pop                                the tiny pop (ONE job at a time)
     --text --dim                         ink
     --nav-bg                             translucent sticky-nav background
     --maxw --radius                      layout constants

   Fonts ride the araya-brand.css @import (Space Grotesk / Inter) — pages
   must NOT add their own Google Fonts <link> (one source only).
