/* =====================================================================
   Low-Key, High Spirits Happy Hour · OPTECH 2026
   Co-brand design system for Apartment List, Flex, Grotto and Resi.
   Partners always appear in alphabetical order.

   Principles
   1. Neutral by default: ink, white and cool greys carry every surface,
      so the base belongs to no single host.
   2. Four colors, blended: partner signatures appear together as soft
      aurora gradients and overlapping circles. Never as color-coded
      bars, stripes or edges.
   3. Ink for action: buttons, links and focus states are ink, so no host's
      color ever means "click here".
