/*
 * PIE API docs — hub (tokens align with scalar-brand.css / PIE canvas).
 *
 * Logo usage:
 * - Hero + favicon + sidebar mark: full-colour mark (streamline-logo-fullcolour.png) on dark canvas — primary brand.
 * - White assets (streamline-logo-white.png) — use only where you need a monochrome mark on busy or coloured UI chrome;
 *   the dark docs canvas favours full-colour or white; we standardise on full-colour for customer-facing surfaces.
