Fix theme connection problems

Invalid or expired secret

Ask the merchant to create a current theme development secret, then run theme connect again. Do not keep retrying an old secret.

Theme key not allowed

The secret belongs to a different permitted theme key. Check the key under themes/ and in theme/storefront.json. Use theme rename when the local theme identity genuinely needs to change.

Connected to the wrong store

Run theme disconnect, obtain the correct store's development secret and reconnect. Disconnecting does not change any uploaded or live theme.

Secret exposed

Ask the merchant to replace it. Never commit .upstorr-theme/, paste a real secret into documentation or send a Workbench launch URL publicly.
