This diagram maps the stages of an empath–narcissist relationship where the narcissist stays, using a Mermaid state diagram. It visualizes paths from idealization through devaluation and control, then to boundary-setting and a stable outcome, while also showing regression, submission, and separation routes. The page loads `diagram.mermaid` via `fetch` and renders it with the Mermaid library, applying custom styling through `mermaid.initialize` and direct SVG manipulation.
