Task Completion Checklist

When completing a task in this project:

Code style: Follow existing spacing conventions (spaces inside brackets/parentheses)
No build step: PHP changes take effect immediately (no compilation needed, except SCSS)
SCSS: If admin styles were changed, SCSS needs to be recompiled
Test manually: No automated tests - verify changes work by describing what to test in browser
Database: If DB schema changes are needed, document them (no migration system)
Git: Commit changes with descriptive message
Security: Be careful with SQL queries, XSS, and session handling
