/* Signal Tools Co. — Pro Knob store styles.
   Level-2 textured direction: layered depth, ghosted B/W Rack backdrop, grain,
   framed faceplates, strong static teal glow on the featured plan.
   Motion is near-static: only a gentle load fadeUp (reduced-motion respected).
   Same brand tokens — no new colors. Real captured screenshots stay as the
   product images (the <img> elements are untouched). */
