/* Sound Lab's page (slop.kitchen/soundlab, tools/soundlab.mjs): the app's own look, not LAST LIGHT's. Its dark
   slate panels, the mint of PLAYING and of a lit step, the amber of a hit pad and the analyzer's spectrogram
   colours; plain system type with monospaced labels, like the hardware it imitates. The slop.kitchen
   wordmark uses the main site's display font. */
