README artwork

Regenerate the light and dark architecture illustrations from the repository root:

bun --filter @sixb/docs generate:readme

The exporter reuses the docs landing page's FrameworkStack.tsx artwork, colors from homeWalkthrough.css, and connector logos. It arranges the layers horizontally and embeds the logos so each SVG renders independently on GitHub. Edit the source, then regenerate both variants instead of editing the SVGs directly.

Atlas and app screenshots show the local examples/northline project with fictional demo data. When refreshing a screenshot, capture the same view in light and dark mode and keep its existing filename pair so the README continues to follow the reader's theme.
