/* =====================================================================
   Instrument themes — cool neutral, anti-cream.
   Colorimetry is judged against a neutral grey surround, so the chrome
   is achromatic and the measured pad colors are the only chroma.
   Graphite is the default; [data-theme="light"] is the cool-light toggle.
   Overriding the vendored brand --color-* tokens re-derives the whole
   semantic layer (which is color-mix over them) for free.
   Fonts are system stacks so the air-gapped build needs no web fonts.
