/*
  Design tokens — aSpace static rebuild
  Brand source of truth: planning/ref/aSpace-Brand-Manual.pdf
  (+ .cursor/rules/brand-manual.mdc). Prefer the brand manual over
  older planning/design-system.md notes when they conflict.

  Colors are declared in two tiers:
    1. Brand palette  — the raw, approved aSpace values. Never used directly
                        by components.
    2. Semantic roles — what components actually reference. Rebranding means
                        remapping this tier, not editing components.
  Values suffixed -dark/-light/-soft are tints or shades derived from the
  brand palette to meet WCAG AA contrast in a specific role.
