Everything here uses fictional data only. It spins up a throwaway MariaDB on a private socket and PHP's built-in server, so nothing touches a real database.

D=$(mktemp -d); cp -r . $D/tinker && cp scripts/demo/router.php scripts/demo/seed.py scripts/demo/capture.py $D/
cd $D
printf 'DB_HOST=localhost\nDB_USER=root\nDB_PASS=\nDB_NAME=ticketing_system\n' > tinker/.env

mariadbd --no-defaults --datadir=$D/db/data --socket=$D/db/sock --skip-networking --user=root &
mariadb --no-defaults -S $D/db/sock -e 'CREATE DATABASE ticketing_system CHARACTER SET utf8mb4'
(cd tinker && php -d mysqli.default_socket=$D/db/sock migrations/migrate.php)
python3 seed.py && mariadb --no-defaults -S $D/db/sock ticketing_system < seed.sql
php -d mysqli.default_socket=$D/db/sock -S 127.0.0.1:8300 -t tinker router.php &
python3 capture.py          # screenshots + GIF -> docs/img/

The app trusts Authelia Remote-User headers, so capture.py sends them directly. Requires playwright and pillow.
