/*
  learn-dev theme: Catppuccin (DEFAULT)
  Palette: Catppuccin Latte (light) / Mocha (dark), official values from
  https://github.com/catppuccin/palette
  Values marked "adjusted" are darkened from upstream to reach the WCAG 2.1
  AA contrast ratio of 4.5:1 on --color-bg; every pair is documented with
  its computed ratio in docs/design/theme-exploration.md
  Both themes define the SAME token names: switching theme = swapping the
  <link> to theme-soft-paper.css (no runtime switcher in v1).
