Engineering a shared visual language at scale: design tokens, semantic color systems, typographic modular scales, 8-point spatial grids, icon ecosystems, production component libraries, systematic naming conventions, responsive reflow, and enterprise governance.
A Design System is not merely a Figma UI kit or a front-end component repository. It is the comprehensive, single source of truth that unites product design, software engineering, and brand strategy into a unified ecosystem. It encompasses guidelines, reusable UI components, design tokens, code implementations, and governance protocols.
Static or interactive vector components, variants, and color styles in design software for mocking up user interfaces.
Documented collections of user interface solutions to recurring problems (e.g., checkout flows, modal behavior, search filters).
The living infrastructure connecting Figma UI kits, coded React/Vue/Swift components, design tokens, accessibility standards, and governance.

| Badge / Pill | tone, format |
Neutral, Success, Warning, Danger | Soft, Solid, Outlined | <Badge tone="success" format="soft">Live</Badge> |
| Modal | size, dismissible |
Sm (400px), Md (560px), Lg (800px) | True, False | <Modal size="md" onClose={handleClose}> |

MAJOR.MINOR.PATCH. A PATCH (v1.0.1) addresses bug fixes or non-breaking contrast updates. A MINOR (v1.1.0) adds backward-compatible new components or props. A MAJOR (v2.0.0) introduces breaking changes—such as renaming core token variables, deprecating a component API, or overhauling global layout architectures.
