/* card-art.css — feature 007 / US2 — the cream-and-gold envelope mini-replica.
   Mirrors useful-new-design/useful/project/styles.css:527–697.

   Three sizes selected by adding a class to the .card-art root:
   .card-art-xs — stat-strip thumbnails (~80 px wide), corners + hearts hidden
   .card-art-md — gallery tile preview (default tile body)
   .card-art-lg — Card Edit live-preview pane (largest)

   Sizing is driven by --art-base (text scale) and --art-display (headline
   size). Each size class sets these two custom properties.

   All values from tokens.css. No literals beyond rgba(...) opacities used
   for the gilt double-border (matched verbatim from the design pack so the
   inset-shadow stack reproduces exactly). */
