besbara bca1a6a407 Keep finger pan/zoom working after using the pen 
After writing with the pen, fingers could no longer navigate:
- every touch was ignored for 5 s after any pen activity (and for as long
  as a hover-capable pen stayed near the screen),
- after that, a one-finger drag on a page drew ink instead of panning,
- a one-finger drag on the background did nothing while an ink tool was on.

Once a pen has been used, fingers now only pan and zoom. The 5 s session
and hover lockouts only block finger ink; touches are still rejected while
the pen is down, for palm-sized contacts and within 150 ms of pen activity.
A finger drag off the page always pans.

README.md

Papure

Lecture notes as a tree of pages ("comb") — live-preview markdown underneath, vector ink on top — stored as one dual-layer PDF per canvas and synced through a GitHub repo. See spec.md for the design.

Run

npm install
npm run dev        # http://localhost:5173
npm test           # unit tests (tree, markdown, PDF round trip, sync against a fake GitHub)
npm run check      # type-check
npm run build      # static PWA in build/ — serve it from any static host (HTTPS for PWA install)

Using it

  • Tools (bottom bar): Text T, Pen P, Highlighter H, Eraser E, Import PDF, Undo/Redo, zoom. The pen's eraser end erases too.
  • Pages: the grey "+" tiles next to the active page add a page there; Alt+Arrow moves to (or creates) the neighbour. Right-click a page or use its ⋯ button to insert, resize or delete it.
  • Importing a PDF into a non-empty canvas shows every free spot; click one to place the chain. Into a blank canvas it simply replaces the empty page. The Files panel can also import a PDF as a new canvas.
  • View: wheel/trackpad pans, Ctrl+wheel or pinch zooms, Ctrl+0 fits the page, Ctrl+9 shows the whole tree, space-drag or middle-drag pans.
  • Sync: Settings → Sync. Use a fine-grained token with Contents: read & write on the repo. Edits autosave locally; pushes happen every N minutes and on Ctrl+S / the sync button. Conflicts: newer wins.

Layout

  • src/lib/model — page tree (pure functions: insert/remove/flatten/layout).
  • src/lib/editor — markdown analysis shared by the CodeMirror live preview and the PDF text layout.
  • src/lib/pdf — PDF writer (vector text, Ink annotations, embedded source-of-truth files) and reader.
  • src/lib/ink — stroke recording/outlines and palm rejection (ported from palm-rejection-test.html).
  • src/lib/storage, src/lib/sync — IndexedDB vault and GitHub sync.

Fonts in static/fonts are pre-subset (scripts/subset-fonts.sh) because pdf-lib's own subsetter drops glyphs.
