/* Slabsmith Explorer — dark industrial design system.
   Locked to dark: the slab photographs carry the color, the chrome stays neutral.
   Class names are the contract app.js renders against. Do not rename .layout-*,
   .zoom-*, .slab-card, .selected, .loading, .missing.

   Two rules that look like style but are load-bearing:
   - .layout-figure must NOT declare `fill`. Figure fill comes from the inline
     SVG attribute (the contour color groups), and CSS would override it.
   - .layout-side-hit needs stroke:transparent + stroke-width:18 + pointer-events:stroke,
     or side selection in the layout viewer stops working. */
