Analyze recent commits for high-severity bugs and submit safe fixes

Thought1s

I’m auditing the recent commit range for high-severity regressions and will only patch issues with concrete evidence and a safe validation path.

Worked for42s

No high-severity bug was found in the recent commit 9fc3023 (feat(web): add responsive plant showcase site). I reviewed the full diff against 69f4c14, scanned for risky browser patterns (script, event handlers, forms, storage/cookie/fetch usage, insecure URLs), parsed index.html, ran git diff --check, and confirmed all four external image URLs return HTTP 200; with no confirmed severe issue, I did not submit a speculative PR.
