• [nitpick] Revise this bullet for clearer parallel structure, e.g., 'An iOS device (iPhone or iPad) running iOS 15 or later with a Secure Enclave.'

- An iOS device (iPhone or iPad) running iOS 15 or later and has the Secure Enclave.

docs/chia-signer/faq.md:30

• [nitpick] Consider refining the phrasing 'Currently, no.' to a more descriptive statement, e.g., 'No, the Chia Cloud Wallet and Chia Signer app cannot be used on the same device for security reasons.'

Currently, no. For security purposes, you need two separate devices: one for accessing your Chia Cloud Wallet (e.g., a computer or another phone) and a separate iOS device with the Chia Signer app installed. This functionality (using both on the same device) is planned for a future release.
