Reviewer's guide (collapsed on small PRs)

Reviewer's Guide

Adds a new unit test suite for the UndoManager to cover initialization, push/pop behavior, clear, and max-history pruning, plus a few small style-only guard/handler changes in UI and export code to use braced single-line conditionals and continues.

File-Level Changes

Change Details Files
Add unit test coverage for UndoManager behavior, including history management and pruning.
  • Create a new undo_manager.spec.js test suite targeting the UndoManager class.
  • Test initialization state, including default history and pointer behavior.
  • Test push/pop operations to ensure undo/redo stacks are correctly maintained.
  • Test clear behavior to ensure history and indices reset as expected.
  • Test max-history stack size pruning logic when the history limit is exceeded.
tests/unit/undo_manager.spec.js
Normalize single-line conditional statements in UI and export components to consistently use braces.
  • Wrap early-return guard in handleIncomingFiles with braces to match project style and reduce ambiguity.
  • Wrap grid row/column assignment guards in normalizeGridInputs in braces.
  • Wrap target existence guard in grid stepper click handler in braces.
  • Wrap toolbar button click handler assignments in braces in LayoutRenderer.
  • Wrap URL-absence continue guard with braces in ExportService export loop.

Hey - I've left some high level feedback:

  • The changes adding braces to existing one-line conditionals in UIManager, LayoutRenderer, and ExportService are unrelated to the UndoManager tests; consider reverting these or moving them into a separate formatting-focused PR to keep this change scoped to testing.
  • For the newly braced if/continue and if/return blocks, consider placing the body on the next line for consistency with the surrounding code style and improved readability.
