  ✨ NEW IN v1.1 — PRESENTATION MODE
  Turn any Markdown document into a live slide deck. Press F5, use --- to separate slides, and you have a full-screen, distraction-free presentation. No PowerPoint required.
  
  🎬 PRESENTATION MODE
   • Three view layouts in one click: Split (editor + preview), Preview Only (hide raw Markdown), and Presentation (full-screen immersive)
   • Press F5 to instantly start presenting — Esc to exit
   • Any --- (horizontal rule) on its own line splits your document into a new slide
   • Navigate slides with ← / → / ↑ / ↓ / Space, or click the on-screen prev/next buttons
   • Slide counter and clickable dot indicator show your progress
   • Auto-hiding controls — top bar and slide navigator fade away after 3 seconds and return on any mouse movement
   • Larger, more readable typography automatically applied in presentation mode
   • Works on any size screen — the preview scales beautifully
