  // The rangefinder digital look (M/Q/SL) is not a film stock, so it ships as its own

  //   CLASSIC — the stock character: deep solid darks, natural shadows, rich but
  //     quiet colour. Its micro-contrast is CLARITY (a local unsharp mask in both
  //     renderers), never a global saturation boost, and a whisker of grain
  //     keeps it feeling like film rather than digital sharpness.
  //   VIVID — the same channel separation opened up for the digital era: lifted
  //     exposure, lifted shadows, a little colour. It reads bright and flattering
  //     straight off the shutter, no editing pass needed.
  // Both share the 'leica'/'leica-vivid' matrices; the tonal half is the sim's
  // own adjustments, which every apply path now carries into the panel.
