Two critical issues on the Spanish-language teaching page and sitemap left 66% of the site unindexed and presented broken download links to Spanish-language users.

Broken links — teaching-es.html

Courses 2–4 had <a download> links pointing to six non-existent PDFs/PPTXs. Aligned behavior with the English version:

• Courses 2 & 3 (Negotiation Skills, Digital Privacy Law): replaced broken links with greyed-out <span> placeholders at opacity: 0.5
• Course 4 (Peace Innovation): replaced missing file links with links to the actual existing lesson pages (lesson_peaceinnovation-l1.html, lesson_peaceinnovation.html)
