/* sounds of — a collection of favourite mixes
   ink-navy ground · one accent per collection · didone wordmark / grotesque / mono

   The wordmark is the signature: a roman cream prefix ("Sounds of") completed by
   an italic accent-coloured suffix naming whichever collection is in view. With
   one collection it simply sits there; with several it becomes a live index. */
