`pineal` is a catalog of specialized painters — cartesian, polar, mesh, treemap, phosphor, flow, heatmap, stream, financial, hexbin, contour, bars — over **one painter abstraction**, the `Canvas` trait. Any program can push shapes to a pineal and get pixels without carrying its own graphics stack. The whole chain `core → render → painter` is **agnostic of the backend**: the same painter draws to vello/Llimphi on screen, to software PNG/SVG/PDF offline, or straight to the GPU for millions of primitives.
pineal **does not compute — it only draws.** Simulation lives elsewhere; pineal turns the output into pixels. It's the hammer, not the carpenter.

## How dependencies work
This is a clean, light front-door: pineal's only external dependency is the [Llimphi](https://gitea.gioser.net/sergio/llimphi) UI framework, pulled as a git dependency. No monorepo clone, no vendoring — `pineal-core`/`render` are backend-agnostic and the on-screen path is the only one that touches Llimphi.
