<Note>
  `points/pressures/eraseLineTrailNums/flagDraw/markPenDirection/recognPoints` are all [`ElementDataAccessor`](/en/api-reference/supernote-plugin/types/trail-data-accessor) accessor objects, not full arrays. Fetch data asynchronously via `size()/get()/getRange()` to avoid JS memory issues caused by transferring large point sets at once.
