PPT slides now annotate with the single performant inking engine (PenCanvas) instead of the old ink_canvas, per "all note features on the pen-first canvas". - PenSlideScreen: per-slide normalized strokes over each slide image, prev/next + slider nav, undo/redo, shared M3 palette, and the pressure curve / eraser size+mode / palm rejection from the shared canvas. - slide_export: pure, tested export geometry. Because strokes are now normalized to the page rect, the PDF exporter maps them straight into each slide's draw rect — fixing the old exporter's known ink misalignment (it guessed live-widget size). - Route PPT import + open -> PenSlideScreen; delete the dead old ppt_annotator_screen. (ink_canvas/annotation_toolbar remain for split_view, the last old-canvas screen.) Tests: slide_export geometry (4). flutter analyze: 0 issues. Suite: 269/269.
