In `@src/routes/docs/products/functions/functions/`+page.markdoc:
- Around line 165-168: Update the wording in the "## Timeout {% `#timeout` %}"
section so units are consistent: change the phrase "For synchronous functions,
there is a hard limit of 30s." to use the full word "seconds" (i.e., "30
seconds") to match "900 seconds" used earlier; edit the sentence containing
"hard limit of 30s" in the +page.markdoc section to read "hard limit of 30
seconds."
