* Added Mermaid syntax highlighting in the Pro editor, covering diagram types, directions, sequence keywords, styling directives, Gantt/data keywords, Git graph, requirement diagrams, C4, architecture, block syntax, and comments.

* Fixed an issue where the current Mermaid file might not render automatically when opening the app for the first time.

* Fixed PNG export naming so exported .png files now use the current Mermaid document name.

* Improved editor and preview reliability during app startup, document switching, and export workflows.

- **LM Studio support** — Choose Ollama or LM Studio as your local LLM engine. Set a custom endpoint for each and pick your model from Settings.

- **First-launch LLM setup** — New Pro users see a short onboarding screen: configure your LLM (Configure) or skip and set it up later (Skip). If you skip, the Pro panel shows a clear “not configured” message with a link to Settings.

- **Streamlined Settings** — LLM (Pro) section with Engine picker (Ollama / LM Studio), endpoint fields, model list, and “Refresh models.” Prompts are no longer in Settings. Open Source Licenses and About are in Settings under Legal and at the bottom.

- **Stability** — License viewer resource path fixed so the in-app Open Source Licenses page loads correctly.
