/**
 * Document transforms on suggestions — pure functions over a transaction.

 * Every transform marks its transaction as internal (never tracked, never locked) and keeps it out
 * of the undo history: undoing a commit, an accept or a reject would leave Velt and the document
 * disagreeing about the suggestion.
 *
 * Marks are removed by INSTANCE (the suggestion's own wrapper), so an overlapping suggestion on the
 * same text is left alone.
