Server-Side Change Test Page
This content is generated in getServerSideProps and holds steady for a 30-second window before changing, so the raw HTML response changes between checks without any client-side JavaScript.
Current word: golf
The window is short enough that two requests moments apart (e.g. adding a local job) see the same content, but requests a monitoring interval apart see a real change. Tune it with ?intervalSec=N if your check interval is shorter than 30s.
