/*
 * Vivestay public website — design system (RM000026 / SPEC000016).
 *
 * Extends the Vivestay product identity (operator console, RM000009):
 * white surfaces, Vivestay blue as the action colour, restrained orange
 * accent, generous spacing, subtle borders and shadows, accessible
 * contrast. Marketing additions: a deep navy for hero/footer bands and a
 * soft blue canvas. System font stack; no external resources of any kind.
