Haapy 092d27beab What persists: every card (kind, position, size, title, note text, ptyId, z-order) + viewport pan/zoom + maxZ counter, ...

in a single board.json under app_data_dir() (~/.local/share/{appName}/board.json on Linux).

  Write pattern: tmp file + atomic rename, debounced 400ms. A crash mid-write can't corrupt the existing file; worst
  case you lose ~400ms of recent edits.

  Read pattern: load on app start, gate the Canvas render on the result. Missing file → default welcome board. Parse
  error → log and fall back to default (won't overwrite the bad file until the user makes changes; actually it will save
   over it after the next change — if you want to preserve a corrupt file for recovery that's a one-line tweak).

  Terminal caveat: live PTY processes die with the app session, so sanitize() in App.tsx clears every terminal card's
  ptyId on load. Each terminal card respawns a fresh shell on mount via the existing pty.spawn path. The card's
  position, size, and title are preserved.
