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).

2026-09-05 — Equal Earth map projection

• Problem: The members map used an unprojected longitude/latitude layout that visually exaggerated land areas at high latitudes.
• Root Cause: The map’s master World layer did not specify a projected display CRS, so tmap drew the source WGS 84 coordinates directly.
• Solution: Set the master map CRS to Equal Earth (EPSG:8857); tmap reprojects the world polygons and both current/past member point layers together.
• Result: The “Where we are from” map now preserves relative land area while retaining the existing locations, colors, sizing, and styling.
• Files Modified: members.qmd (not yet committed).
