Refactor to Notemark: minimalist markdown editor app
- 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

# Notemark — .NET 10 Blazor Server Specification (Markdown Editor + Preview + Share)
|
||||
|
||||
## 0) Goal
|
||||
Notemark is a minimalist Markdown editor web app built with **.NET 10 Blazor Server**.
|
||||
|
||||
- First visit generates a **GUID sessionId**
|
||||
- Markdown is saved as a **file on disk** (no database)
|
||||
- Fullscreen editor, optional preview split view
|
||||
- Share links:
|
||||
- **Readonly** → preview only
|
||||
- **Editable** → preview only + Edit button
|
||||
|
||||
---
|
||||
|
||||
## 1) Tech Stack
|
||||
- .NET 10
|
||||
- Blazor Server
|
||||
- Markdown rendering: Markdig
|
||||
- HTML sanitization: Ganss.XSS (HtmlSanitizer)
|
||||
- Persistence: File system only
