/* ==========================================================================
   One World Connected
   Design system sampled from the logo artwork (see the OWC palette artifact).

   Four rules this file obeys, and you should too when extending it:
     1. White NEVER sits on Signal Yellow (1.75:1). Yellow takes Ink text.
     2. Yellow fills, amber writes — on light grounds yellow is a background
        colour; brand-hue TEXT uses Amber Deep / Amber Dark. On Night the
        rule inverts and yellow becomes a AAA text colour.
     3. Yellow is capped near 15% of any screen; warm neutrals carry the rest.
     4. Yellow is never the only signal — pair it with a label, icon or shape.
