Website Language Switcher Checker — illustrative example

INPUT
Supplied check: /tools/example/ is English. Its French link points to /fr/tools/example/, which returned HTTP 404. No intended replacement known.

RESULT
Source page: /tools/example/
Language choice: French
Destination: /fr/tools/example/
Observed response: 404, unavailable.
Action: confirm the intended translated route or remove the unavailable choice. A French homepage would not establish a translation of this tool.

REVIEW
Check language links against actual destinations and page labels. Do not advertise a translated tool when only the site homepage exists in that language.

This is a teaching example, not a live execution record.
