🌟 Key Highlights

• Native Windows Desktop Experience: Packaged with Electron, custom frameless titlebar with native Windows 11 window controls (minimize, maximize, close), and drag regions.
• CodeMirror 6 Engine: Low memory footprint, instantaneous startup, fold gutter, bracket auto-closing, active line highlighting, and multi-selection.
• Modern Markdown Pipeline: Unified + Remark + Rehype AST architecture rendering GitHub alerts ([!NOTE], [!TIP], [!WARNING], [!CAUTION]), KaTeX mathematical notation, and GFM tables.
• Interactive Code Cards: Automatic language badge detection with one-click clipboard copying.
• Live HTML Sandbox with DOM Morphing: Sandboxed iframe previewing live HTML/CSS with idiomorph differential DOM updates and an integrated debugging console.
• Piecewise Linear Scroll Sync: Bidirectional scroll interpolation matching CodeMirror lines directly to preview DOM elements via source-map line attributes.
• Clean Engineering & Reliability: Strict TypeScript typing, modular component architecture, zero runtime bloat, and unified diagnostic logging.
