Add a travel guide: **Barcelona (Spain)**

1. Create a new guide page `barcelona-guide.html` (follow the style of the existing `guide.html` pages).
2. List it on the **Europe** region page (`europe-region.html`) by adding one destination row. Follow the instructions in the comment at the top of that file's destination list: insert one self-contained list-item block in alphabetical order

Start by comparing the existing guide.html pages to follow their style, then read the destination-list comment in europe-region.html. Create barcelona-guide.html for Barcelona, add its self-contained destination list item in alphabetical order on europe-region.html, and verify the page and link match the existing layout.
