### Package Dependencies

- **Web app** depends on: `@tiny-svg/svg`, `@tiny-svg/code-generators`, `@tiny-svg/ui`
- **Figma plugin** depends on: `@tiny-svg/svg`, `@tiny-svg/code-generators`, `@tiny-svg/svg-packer`, `@tiny-svg/ui`, `@tiny-svg/utils`

**Important:** After modifying any package in `packages/`, run `pnpm build:packages` before building apps.

## Deployment

Deployed on **Vercel** for full SSR support. Cloudflare Workers not supported due to MDX runtime restrictions (`eval()` prohibited).
