Configuration reference

~/.tg.json stores CLI state, not a complete target configuration. Unknown keys survive writes; missing or malformed files recover with defaults.

Field	Type	Owner
customThemes	string[]	Theme discovery during generation.
lastAppliedTheme	theme ID or null	Generation and application flow state.
favoriteSeedColors	{ color, variant }[]	Favorites; legacy string favorites migrate on read.
lastUsedSeedColor	hex color or null	Seed generation.
lastUsedVariant	variant or null	Seed generation.
lastUsedThemes	optional { dark?, light? }	Mode-specific selection state.

State writes use a same-directory temporary file followed by rename. This is atomic replacement for the normal state path, not a backup or rollback mechanism.

Read the configuration guide for behavior and recovery details.
