Make Surface remote debugging and classroom workflows viable: always-on structured logs with one-click zip export, a single AppShell chrome, OOXML PPTX/DOCX annotation without LibreOffice, and a first-class sticky board. Also drop spike/legacy ink widgets and tighten pen feel (predictor, PenInfoHistory, page-tile layer). Co-authored-by: Cursor <cursoragent@cursor.com>
