/* The Studio portal. Brand tokens from BRAND.md, 22 August 2026.
   Poppins 600 / DM Sans 400.

   FOUR COLOURS ONLY, set by Lisa 11 September 2026: black, orange, grey,
   white. No teal. Status is therefore carried by WEIGHT, not by hue:
   black is what is due, orange is what is with Lisa, outlined black is
   answered, flat grey is missed, hairline grey is ahead. */
