Every range rule now names `input[type="range"]` itself, so the class-only WB
rules tied with the plain hairline that follows them and lost — both sliders
were drawing the same grey line as every other knob, and their node sat a pixel
off the thicker track. Measured on the panel: the gradients are back in amber
and blue, and the ring is centred on the line.
