   gh-audio-player — styles

   Theme it entirely by setting these custom properties on .gh-audio-player
   (or any ancestor). Fallbacks assume a light background.

     --gh-accent        main brand colour (play button, fills, viz)  [red]
     --gh-accent-dark   darker accent for the play-button hover
     --gh-text          primary text colour
     --gh-tan           secondary/label colour
     --gh-bg            panel background
     --gh-radius        corner radius
     --gh-font          serif font for the track title

   Faint greys are neutral rgba() (fine on light backgrounds). For a dark
   theme, override the element rules or set the greys explicitly.
