A new "Creator's voice" section was added to the footer, featuring a paragraph about a handwritten-style font and a link for font recommendations. Additionally, both en.html and index.html were updated to include client-side validation in the form submission handler, preventing submission if the "user_url" field is empty or whitespace.

Cohort / File(s)	Change Summary

Poem

In the footer’s gentle space,
A rabbit’s paw leaves a trace—
Handwritten fonts now hop in view,
With links for you to share a few!
Forms now check for empty trails,
No more blank or whitespace tales.
🐇✨
