 *   teal     #0E8F8A (light) / #3CC4BD (dark)   Summit Teal — the single brand accent
 *   copper   #C08552 (light) / #D49A66 (dark)   warm metallic highlight, used SPARINGLY (achievement only)
 *   granite  #16181C                            dark canvas (the premium register)

 *
 * Dark-mode-first per the app's design intent; light via prefers-color-scheme.
