Fix missing slide background images on GitHub Pages

jeremymanning · jeremymanning · commit cc470ea3f66b · 2026-01-11T23:40:12.000-05:00
- Use cp -rL in deploy workflow to follow symlinks
- Add themes symlinks to all week directories (week2-week10)

The CSS references theme assets with relative paths, but symlinks
weren't being resolved during deployment. This caused background
images (background_geometry.svg, conversation_green_32pct.png) to
be missing on the live site.
