Environment - Keel

Variable	Default	Does
`KEEL_HOME`	`~/.keel`	Keel’s folder: database, synced copy, config, backups, history
`KEEL_DB_URL`	`file:` + `KEEL_HOME/keel.db`	Use another database: another file, or `libsql://...` directly. Overrides `keel db connect`
`KEEL_DB_TOKEN`		Token for `KEEL_DB_URL`, or instead of the stored one
`KEEL_BACKUP_KEEP`	`14`	How many daily backups to keep. `0` turns them off
`KEEL_BACKUP_DIR`	a `backups` folder next to the database	Where daily backups go
`KEEL_THEME`		`light` or `dark`, overriding `theme` and detection
`KEEL_PORT`	`4242`	Port for `keel serve`
`KEEL_SECRET_STORE`	system keyring	`file` keeps tokens in a file only you can read (headless servers)
`NO_COLOR`		Plain output without colors
`FORCE_COLOR`		Colors even when output isn’t a terminal

How the CLI picks colors

KEEL_THEME, then the saved theme setting, then COLORFGBG, then it asks your terminal for its background color, then dark. Output that isn’t a terminal (a pipe or a file) has no colors unless FORCE_COLOR is set.
