- *
- *   primary        #0e6b64 (deep teal: top bar, active nav, tabs)
- *   primary dark   #0a4f4a (pressed / dark variant of the primary bar)
- *   primary light  #17857c (hover / light variant of the primary bar)
- *   accent         #0d7d70 (light-scheme links, ~5.0:1 contrast on white)
- *   accent light   #6fd0c2 (dark-scheme links, contrast on the slate bg)
