   Jazz Harmony Analyzer — analyzer.css
   Shared by /jazz-harmony-analyzer/ and every concept page under it.

   The tool takes the author-level neutral palette from the landing page:
   no book owns it, so it carries no book's accent. The colour that does
   carry meaning here is the harmonic function — tonic, predominant,
   dominant — and those hues are the same ones the books use for the same
   ideas: sage for arrival, orange for tension.
