**Problem**: After migrating Paper Dynasty database from SQLite to PostgreSQL, card generation endpoints returned 'Internal Server Error' with jinja2.exceptions.TemplateNotFound for 'player_card.html'.

**Root Cause**: The storage/templates/ directory containing card rendering templates (player_card.html, topright_batter.html, topright_pitcher.html, etc.) was not included in the production deployment. The directory is gitignored and was lost during migration.

**Solution**:
1. Recovered templates from old server: `scp pd-database:/home/cal/container-data/pd-database/storage/templates/*.html ../database/storage/templates/`
2. Updated .gitignore to allow templates: Add `!storage/templates/` after `storage/`
3. Force-added to git: `git add -f storage/templates/`
4. For immediate fix, SCP'd directly to production: `scp -r ../database/storage/templates/ akamai:/root/container-data/paper-dynasty/storage/`
5. Restarted API: `ssh akamai 'cd /root/container-data/paper-dynasty && docker compose restart api'`

**Templates Required**:
- player_card.html (main card template)
- topright_batter.html, topright_pitcher.html (position-specific headers)
- results_vl.html, results_vr.html (batting results vs L/R)
- result_columns.html, style.html (layout/styling)

**Prevention**: When deploying database container updates, verify storage/templates/ is mounted or included in image.
