/* ============================================================================
   ATOM Design System — Preview canvas contract
   ----------------------------------------------------------------------------
   Every card preview authors against a fixed 400x225 canvas
   (the card frame's 16:9 box at its largest rendered size). preview-loader.js
   sets --atom-preview-scale per card so the canvas scales down to whatever
   width the grid gives it. That means every preview can be written in plain
   px, and stays pixel-consistent across the 2-col and 3-col breakpoints.
   ========================================================================== */

/* The fallback lives in the var() call, not as a declaration here. Declaring
   --atom-preview-scale on .atom-preview itself would beat the value
   preview-loader.js sets on the parent frame — an element's own declaration
   always wins over an inherited one — and every canvas would render unscaled. */
