## 1. Instructions for AI Agents: Save Atunus Home Design System Locally in 1 Step

### Workflow A: Coding Agent WITH Terminal / Shell Access (Claude Code, Codex, Antigravity, Cursor, Windsurf)

Run ONE single zero-dependency Python 3 command (works on Windows, macOS, and Linux; automatically verifies SHA-256 `b98fa47d986ecb3d...` and extracts all `882` files):

```bash
# Save complete Atunus Home Design System locally to ./design-system/atunus-home:
python -c "import urllib.request as u; exec(u.urlopen(u.Request('https://atunus-home-ds-33405.pages.dev/save-ds.py', headers={'User-Agent':'Mozilla/5.0'})).read().decode('utf-8'))" ./design-system/atunus-home

# Or install directly as a native Agent Skill into ./.claude/skills/atunus-home-design-system/:
python -c "import urllib.request as u; exec(u.urlopen(u.Request('https://atunus-home-ds-33405.pages.dev/save-ds.py', headers={'User-Agent':'Mozilla/5.0'})).read().decode('utf-8'))" ./.claude/skills --as-skill
```

Alternative OS-native 1-liners:
- **curl + Python (Windows 10+ / macOS / Linux)**: `curl -fsSL https://atunus-home-ds-33405.pages.dev/save-ds.py | python - ./design-system/atunus-home`
- **Windows PowerShell**: `$env:DS_DEST="./design-system/atunus-home"; irm https://atunus-home-ds-33405.pages.dev/save-ds.ps1 | iex`
- **macOS / Linux Shell**: `curl -fsSL https://atunus-home-ds-33405.pages.dev/save-ds.sh | sh -s -- ./design-system/atunus-home`

Immediately after saving locally, read inside `./design-system/atunus-home/` in this order:
1. `CLAUDE.md` (or `AGENTS.md` / `SKILL.md`): Brand identity, locked palette, typography, radii, CTA copy, and redlines.
2. `ai-replication-contract.json`: Schema v4.0 W3C tokens, OKLCH canvas tolerance, APCA-W3 contrast floors, and 9 page blueprints.
3. `tokens/tokens.css`, `tokens/semantic-bridge.css`, `tokens/brand-fonts.css`: Production CSS variables and offline WOFF2 fonts.
4. Before delivering any HTML/UI output, run offline self-verification: `python tools/ds_lint.py --target <your-page.html>`.

### Workflow B: Web Chat AI WITHOUT Shell Access (claude.ai Artifacts, ChatGPT Web, Gemini Web)

Fetch the **Single-File Complete AI Pack (`112.6 KB`)** in one HTTP GET:
- `https://atunus-home-ds-33405.pages.dev/ai-pack.md`
