UX Review

You already know Nielsen's 10 heuristics and the Laws of UX. This skill sets the procedure, what to look for in this stack, and the report format.

Scope

Ask for, or infer, what to review: one view, one flow (several views plus the controller actions between them), or a whole feature. Read the templates, their partials, the Stimulus controllers they attach, and the CSS for the blocks they use. Run the app and look at it when a browser tool is available; code alone misses layout, contrast, and timing.

What to check

Work through the table. Each row is a common failure and the code that reveals it.
