/* Modal that hosts the configurator iframe.
   The frame element ALWAYS has its target (open) dimensions in the layout —
   FLIP from the card to the modal is animated via `transform` (translate+scale),
   not by mutating width/height. This keeps the iframe's CSS viewport stable so
   the WebGL canvas inside initializes at full target size and never sees a
   zero-sized framebuffer. (1×1 sizing breaks GL: zero-size textures, incomplete
   framebuffers, etc.)

   States, controlled by aria on `.jc-modal`:
   - aria-hidden="true"  : frame opacity 0, pointer-events none — iframe stays
                           mounted and rendering at full target size, invisible.
   - aria-hidden="false" : frame opacity 1, transform animates from the clicked
                           card's rect to identity. */
