Frontend verification becomes easier when the basic tools are ready before trouble starts.
For me, the starting point is Python tools and Git.
Git keeps the work visible
Before checking anything, I want to know what changed.
git status and git diff are still the fastest way to avoid confusion.
Python helps automate checks
Python is useful for small verification tasks.
It can read files, compare screenshots, inspect HTML, or run simple reports.
Do not skip the visual check
Frontend work is not finished only because the code changed.
Open the page, check the layout, and confirm the thing you meant to fix is actually fixed.
My setup rule
Make verification boring. The easier it is to check, the more often you will check.
