Keep Strudel code as the source of truth. Visual edits should write deterministic changes back to the editor text.
Prefer conservative parsers and explicit fallback behavior over best-effort mutation.
Add or update tests when changing notation parsing, timeline analysis, arrangement recognition, or persistence behavior.
Keep UI changes consistent with the existing editor-focused interface.
Do not commit generated build output, local environment files, or browser storage exports unless they are intentional fixtures.
