/*
  SKIN: linen — Linen — soft warm modern

  Warm neutrals, muted teal primary, generous radii and diffuse depth. The furthest from today: calmer, less industrial, easier on a long day of reading grids.

  Generated by tools/skins/make_skins.py. Ramps are built in OKLCH so lightness steps are
  perceptually even and every family carries matching weight at the same shade. Edit the recipe
  in that script rather than these values, or the next run overwrites your changes.

  Colours are space-separated RGB CHANNELS. Tailwind composes them as
  `rgb(var(--c-x) / <alpha-value>)`, which is what keeps opacity modifiers working.
