/* Chirp Studio. Visual language: an instrument's printed faceplate. Cool aluminium panels (or dark
   graphite), hairlines, small mono labels, graphite knobs with a lit tick ring, square LEDs, segmented
   meters. One accent colour, Delft blue, marks what is active; the readouts styled as the pedal's
   screen glow a lighter blue on black. Two themes: the system's (prefers-color-scheme) unless the
   Theme button picks one, which sets data-theme on <html> (studio.js, setTheme). */
