   Three themes: light (default), dark, wood. Every colour is a custom
   property redefined per theme — there are NO colour literals below the
   token blocks, which is what makes a per-theme contrast audit possible.

     1. Themes / tokens
     2. Base
     3. Header / footer / theme switch
     4. Hero, sections, cards, prose
     5. Controls
     6. The tool: meter, readouts, level, devices
     7. Curve graph, slot heatmap, history
