- Remove Blazor template pages and navigation; redesign layout for fullscreen editor with light/dark theme support
- Add Editor.razor: markdown editor with live preview, auto-save, and share modal for readonly/editable links
- Implement MarkdownService (Markdig + HtmlSanitizer), SessionService (cookie-based, file persistence), and ShareService (token-based sharing)
- Configure DI and cookie policy in Program.cs; add Markdig and HtmlSanitizer NuGet packages
- Include example session and share token data files
- App is now a single-page markdown editor with file-based storage and sharing, no database
