/* "Base Plate Opening" on router base plate product pages
   (functions/woocommerce/base-plate-overlay.php). One plate drawn to scale
   with both center openings concentric (no card around it: a tinted box reads
   as another plate, so the drawing sits flush), a legend with each opening's facts,
   and a status line; the chosen variation lights up and hover / tap / focus
   previews the other. Loaded only on qualifying products
   (functions/core/assets.php), after the product bundle. The active opening
   is the root's data-active ("guide" | "wide"); everything below paints from it.
   --tc-bpo-k (set inline on the root, plate size / 6) scales SVG type and strokes so
   they stay the same size on screen whatever plate is drawn. */
