refactor: rewrite code for improved clarity and consistency#1940
Conversation
Rewrite various code sections across core modules for better readability, more idiomatic patterns, and consistent style: - shape.py: use IntEnum for point style/vertex mode constants, restructure control flow with guard clauses, improve variable naming - canvas.py: rewrite boundedMoveShapes with clearer clamping logic, improve offsetToCenter variable naming, restructure event handlers - app.py: simplify scaleFitWindow with explicit min-based scaling, improve deleteFile/maybeSave flow with early returns, better variable names - label_dialog.py: consolidate flag widget management, extract helper methods - file_dialog_preview.py: extract magic numbers to named constants - brightness_contrast_dialog.py: use descriptive callback naming - __main__.py: use pathlib for file detection - utils/shape.py: minor expression cleanup All tests pass. No behavioral changes.
