Different kinds of evidence
A browser preview, native app window and screenshot answer different questions. A screenshot shows appearance at a moment; it does not prove buttons work.
Specialist viewers and native preview additions depend on the installed build and computer.
- Start the intended preview/application and identify its location.
- Exercise the main flow with realistic input and an error case.
- Check narrow layouts, keyboard use and relevant device sizes.
- After changes, refresh the actual running version and capture new evidence.

Example request
Open the current build, test adding and deleting a note, then reopen it to check persistence. Capture desktop and phone-width layouts and include relevant console errors.
Check the result
- The preview matches current source.
- The main interaction works.
- Mocked data or a missing backend is clearly identified.
Blank or stale previews
Check the process, port, log and browser console before redesigning a blank screen.
A local preview URL may not be reachable on a phone without a supported relay or sharing path.
Your screen may differ by platform and version. Check availability or get help.
