Dark mode by inversion
======================

Rule · bucket: judgment · severity: note · detector: none · since: v0.1.0
Section: Things to avoid
Group: Colour and contrast

Forbidden:
  Flipping to `#000` background and keeping the same shadows and borders

Instead:
  Dark mode is its own ramp: elevated surfaces get *lighter*, shadows lose most of their meaning, and saturated colours need desaturating. If dark mode is out of scope, say so rather than shipping a broken one.
