Introduced GPUIX-native primitives for living vector marks: - A new `<canvas>` custom element in `packages/native/src/custom_elements/canvas.rs` that renders arbitrary JS path commands via `gpui::PathBuilder` every frame natively. - React components `VectorPath`, `OrganicBody`, `VectorEyes`, and `DecorativeStroke` that wrap `<canvas>` with semantic properties (squash, breathe, glance, blink, wiggle). - Rebuilt native animation frame triggers using GPUI's Rust frame loop (`window.request_animation_frame()`), allowing seamless transforms without React's overhead. - Added `examples/marks.tsx` for showcase and `packages/react/src/__tests__/marks.test.tsx` for tests.

Springs moved to #34. Living-marks / OrganicBody / VectorEyes withdrawn — we shipped SVG stamps instead. |

Summary
GPUIX-native primitives for living vector marks, plus a native spring integrator proven in Automaton tonight (living SVG stamps + GELATIN). Transparency already works; this is the next capability.

<svg source>is a monochrome mask tinted bystyle.color(path fill in markup is not the GPU paint).Why
Apps like Automaton currently swap PNG pose frames. These primitives let a body squash, eyes glance/blink, and accent strokes wiggle on the GPU; springs give the gel without CSS tweens.
