/*
  Designed for e-ink: the screen is paper, so white is paper and black is ink.
  Greys dither on most panels, so they are kept to secondary text and hairlines.
  No transitions or animation anywhere: e-ink redraws every frame as a flicker.
  Feedback is the Kindle's own: a pressed control inverts.
  CSS stays conservative (no flex gap, :is, clamp, nesting) for older Kindle browsers.
