   Themes are CSS variables on html[data-theme]: lavender (default, owner's choice D4), light and dark.
   Palette = prototype/index.html with a few text colours darkened so every text pair has contrast >= 4.5:1
   (docs/08 §6; tests/test_theme.py checks it). Font: Montserrat, self-hosted (SIL OFL, see fonts/OFL.txt). */
