QGraphicsView for the viewport, with cuts and the content rectangle manipulated by hit-testing in the view rather than as movable items — the geometry is normalised, so what the screen shows and what the renderer uses are the same numbers at a different zoom. Cuts are edited as polylines: double-click adds one, drag moves it, Ctrl-click inserts a vertex, right-click deletes a vertex or the whole cut. That is how a straight cut becomes the stepped cut Engel needs. Slice boundaries are drawn, not just cut lines, so a trim anomaly is visible before export rather than after. Discarded slices are shaded. Pages preview at 1800px regardless of source resolution, cached per page, because re-reading a 4959x7017 vector render on every slider move is unusable. Autosave is debounced at 800ms and also fires on close. Closes #12 Closes #14 Closes #15 Closes #16 Closes #17 Closes #18 Closes #19 Closes #20 Closes #26
