   1. DARK COLOUR SCHEME
   ------------------------------------------------------------
   The light palette lives in theme.json, so a buyer edits it in
   Styles → Colors like any other theme. Dark mode re-points the
   same preset variables inside a scoped selector, which means
   every block, pattern and core style follows automatically —
   nothing here targets a component by name.

   To restyle dark mode, change the values in this block only.
