The home graph view had breathing room on every side (main px-4 py-2,
the composer docked below in flow, the header above). Per the owner:
- The canvas now owns the whole column — absolute inset-0, from the
sidebar to the right edge of the screen, bottom to top, zero padding.
- The header floats over the graph (pointer-events-none except the
sidebar toggle, so the canvas stays draggable around it).
- The new-session blob + stats bar dock OVER the graph at the bottom,
no gradient scrims anywhere — the graph runs clean under everything
to the very edges.
- The renderer itself is untouched: same canvas, same data, same fit
logic — only its container grew. The composer keeps chat's DOCK
geometry (max-w-[46rem] px-4) so nothing shifts when a session starts.
Verified live in headless chromium (1280×800, sidebar open): canvas
spans x 288→1280 (sidebar edge → right edge), y 0→800 (bottom to top);
the header overlays the top; the dock overlays the bottom with its
content ending 16px above the viewport edge.
