/* Open Academy — color tokens.
   Base palette matches the shipped default tenant theme (src/styles.css) — a
   blue primary + teal secondary academy theme. Every tenant can override
   --brand-primary/--brand-secondary at runtime (ThemeService); the surface,
   border and text variants are DERIVED from those two seeds via
   color-contrast.util.ts (tint mixing + WCAG contrast checks), so a consuming
   design should always read the semantic variables below, never hard-code a
