2026-07-29 — Teaching page and navigation

• Problem: The English website did not have a top-level Teaching tab or a page for the Fall 2026 course.
• Root Cause: No teaching page or navbar entry had been configured.
• Solution: Added teaching.qmd, populated its Fall 2026 section from Fall2026.md, and linked it from _quarto.yml. After the initial implementation, removed the second identical “Time and Location” line inherited from the source.
• Result: Visitors can open concise Fall 2026 teaching information directly from the English site’s top navigation, with the schedule shown once.
• Files Modified: _quarto.yml, teaching.qmd (initial implementation: commit 72084d2; duplicate removal not yet committed).
