Meridian is also built as a living design system rather than a static reference. Using design tokens in Figma, the system is meant to scale and update in place — so when colors, spacing, or components change, they propagate through the file instead of triggering another "final_v3" PDF that half the team never opens. It's built for internal design teams who need a single source of truth, not a snapshot that goes stale the moment someone updates a button radius. The brand guidelines themselves live as an interactive site built in Figma Sites, rather than a slide deck — navigable and explorable, always reflecting the current state of the system.
