# SlickFast
> A deterministic render engine. Not a charting library.
> Spec in, same bytes out. Forever. Charts, boards, and Pages. No headless browser.

## What it does
- Spec in → SVG/PNG or a whole Page. Same spec, same bytes, forever.
- 47 types — bar, line, pie, dashboards, gauges, funnels, calendars, KPIs — one schema.
- A full dashboard (many tiles) is ONE image render.
- Live charts: permanent image URL whose content updates when you re-push the spec.
- Pages: a whole document from one spec, at a public URL. Twin at that URL plus `.json` (the source, not an export). Fingerprint on the Page must match it. Don’t trust us. Check the math.
