# Nci Design System

> Builds National Cancer Institute interfaces with the official NCI Design System Sass, JavaScript, components, templates, CDN bundles, and USWDS foundation. Use for NCI-governed products and respect its registry and compiler constraints; it is not a generic NIH or HHS design system.

# NCI Design System

Build within the system's documented scope and delivery model.

## Before editing

1. Confirm the product owner and that this system is authorized for the target surface.
2. Read [references/implementation.md](references/implementation.md) before installing or changing dependencies.
3. Read [references/sources.md](references/sources.md) when checking versions, provenance, license, or release state.
4. Inspect the existing framework, package manager, asset pipeline, and accessibility tests. Preserve them unless the official integration requires a change.

## Workflow

1. Choose one documented delivery path; do not mix compiled, source, CDN, and framework-wrapper paths accidentally.
2. Pin the dependency or downloaded asset version and keep upstream notices.
3. Reuse official components, tokens, content guidance, and templates before adding custom UI.
4. Extend through documented tokens, properties, slots, Sass settings, or composition. Do not edit vendored package files.
5. Test semantic structure, keyboard operation, focus order and visibility, accessible names, error recovery, zoom/reflow, contrast, and target browsers.
6. Report custom patterns, unsupported requirements, and upstream gaps explicitly.

## Boundaries

- **Scope:** National Cancer Institute products. NCIDS is not a generic NIH or HHS design system.
- **Release:** current public release with authenticated package, CDN, and direct-download paths (see the sources ledger for the version snapshot).
- **Delivery:** GitHub Packages for Sass/JavaScript, pinned CDN bundles, or direct download.
- Do not invent component APIs, tokens, package names, or compliance claims.
- Do not import another jurisdiction's branding to fill a gap.
- A passing component example does not prove the completed service conforms to WCAG, Section 508, the ADA, or local policy.
