/* css/pb/tokens.css — design tokens for the WP1+ "pb" (Partners Brand) screens.
   SOURCE OF TRUTH: the brand block below re-exports Partners.Application.Common.BrandPalette,
   emitted server-side as --brand* by Views/Shared/_BrandTokens.cshtml (ADR-0044). Every other
   token (ink, surfaces, lines, status, radii, shadows, type, spacing, layout, motion) is owned
   HERE — this file, not BrandPalette, is their one source. PbTokensParityTests pins every
   re-export's literal fallback to its BrandPalette constant.
   LOAD ORDER: _BrandTokens.cshtml (emits --brand*) → css/pb/fonts.css → css/pb/tokens.css →
   base.css → layout.css → components.css. Never through bundleconfig.json (see root CLAUDE.md). */
