# Design System — Onboarding + Shared Brand Tokens
The design-system skill is the **shared brand owner** for the markdown-html plugin. Run its onboarding once. Every converter (`md-document`, `md-review`, `md-slides`) reads the resulting config via `config_loader.py` and applies the same 12 CSS custom properties to its output. Without this, conversions render with placeholder defaults — technically functional but unbranded.
This skill ships exactly three Python tools:
1. **`onboard.py`** — interactive (or `--defaults` / `--set` / `--show` / `--reset`) wizard.
2. **`config_loader.py`** — importable customization loader with project > global > defaults precedence and `MARKDOWN_HTML_NO_CONFIG=1` bypass.
3. **`brand_palette_validator.py`** — WCAG-AA contrast checker + HSL palette deriver.
All three are stdlib-only and contain no LLM calls (deterministic per Path-B discipline).
