# Vercel Usage
Design System 2.0 package guide for OpenDesign agents and reviewers.
## Read Order
1. Read this file first to understand the package contract.
2. Read `DESIGN.md` for visual intent, constraints, and anti-patterns.
3. Paste `tokens.css` into the first artifact `<style>` block before writing component CSS.
4. Use `components.manifest.json` for the compact component inventory; open `components.html` when exact selectors or states matter.
5. Inspect `preview/` pages when a visual sanity check is useful.
## Design Highlights
- Geist Sans with extreme negative letter-spacing (-2.4px to -2.88px at display) — text as compressed infrastructure
- Geist Mono for code and technical labels with OpenType `"liga"` globally
- Shadow-as-border technique: `box-shadow 0px 0px 0px 1px` replaces traditional borders throughout
- Multi-layer shadow stacks for nuanced depth (border + elevation + ambient in single declarations)
## Do
- Preserve the schema token names exactly so cross-brand switching stays reliable.
- Use `--accent` for primary actions, links, focus states, and one clear focal element.
- Reuse component groups from `components.manifest.json` before inventing new controls.
- Treat `source/` files as audit evidence for the bundled fixture backfill.
## Avoid
- Avoid raw hex values outside the copied `:root` token block.
- Avoid redefining Tailwind or design-token values independently of `tokens.css`.
- Avoid claiming original upstream source evidence; this package is based on the curated bundled fixture.
- Avoid adding new component recipes that are not represented in `components.html` or `DESIGN.md`.
