Task
Perform frontend QA for the prompt library: search, empty state, clear search, category filter, keyboard and copy. Read the real clipboard and compare full text and newlines. Test desktop 1440×900 and mobile 390×844.

Instructions
Use the current local site if a real defect is found. If it has no suitable defect, create a clearly labeled local training page with a clear-search defect: clearing empties the input but does not restore hidden cards. Never call the training defect a production defect. Freeze the failing fixture and a reproduction before fixing it.

Output
Actual failure, reproduction steps, before screenshot, minimal fix diff, same-condition retest and after screenshot; plus keyboard/focus/clipboard results. Retain first output and revision.

Checks
Search for meeting, try a no-result query, clear, choose coding, use keyboard to reach controls and copy one full prompt. No mock clipboard for acceptance. Keep screenshots and text evidence free of personal data. Do not modify production or the shared prompt component; a separate training fixture is the owned target.
