Prerequisite: Ensure ClerkProvider wraps your app. See clerk-setup skill.

Version: Check package.json for the SDK version — see clerk skill for the version table. This determines which custom flow references to use below.

This skill covers two areas:

1. Custom authentication flows — build your own sign-in/sign-up UI with hooks
2. Appearance customization — theme, style, and brand Clerk's pre-built components
