The auto-laid-out Mermaid flowchart looked rough. Replace it with a
hand-built Anthropic-style diagram: color-coded role cards, a dashed
scene-generation group, and the speculative pre-generation loop.
Each SVG bakes in a dark background so it renders consistently whether
the viewer's GitHub theme is light or dark (theme is per-viewer, not
per-repo). Ship one localized SVG per README (zh/en/ja) to preserve the
existing per-language diagrams, and strip claude.ai artifact residue
(onclick / var() / context-stroke).
