CR-2026-03-23: College Algebra Curriculum — Rollback

Rollback Procedure

The migration is additive (new files created, old page converted to redirect). Rollback by:

# 1. Remove new curriculum directory
rm -rf docs/modules/ROOT/pages/education/mathematics/college-algebra/

# 2. Restore old college-algebra.adoc from git
git restore docs/modules/ROOT/pages/education/mathematics/college-algebra.adoc

# 3. Revert nav.adoc changes
git restore docs/modules/ROOT/nav.adoc

# 4. Revert tracker partial
git restore docs/modules/ROOT/partials/trackers/education/college-algebra.adoc

# 5. Verify build
cd ~/atelier/_bibliotheca/domus-docs && make 2>&1 | grep -E "WARN|ERROR"

Pandoc source files in Principia are unmodified and remain available for re-migration.
