- 저장 (Ctrl+S) downloads <교량명>_교각설계.pzr.json; 프로젝트 열기 reads it
back and regenerates every pier without the source workbook.
- Save status in the header: 저장 전 / 변경 있음 · 미저장 / 저장됨. The
snapshot excludes the history so a save is not counted as a change.
- Auto-backup to IndexedDB 0.8 s after changes while unsaved; on start a banner
offers recovery or discard. Storage failures are reported, not fatal.
- beforeunload warns while there are unsaved changes.
- B1 (default-vs-changed tracking) is not added yet: inputs are not editable
until the 2단계 input cards exist.
- Not verified in a browser (no debuggable Chrome in this session).
