   CONCEPT A — SLATE REGISTER
   Official brand palette: deep slate #2B3F4A, balanced slate
   #63788A, soft slate #D9E0E7, white. Functional accent:
   induction orange #C7500F (the one warm colour the workshop
   itself produces). Type: Big Shoulders Display / IBM Plex Sans
   / IBM Plex Mono. Geometry: the rule and the index. Hairline
   rules only ever encode table structure or caption ledgers.
