-## Optional Dispatch-Owned ChatGPT Sign-In
-
-Import the ready-to-use helpers from `app/chatgpt-auth.ts` when the site needs
-optional or required ChatGPT sign-in:
-
-- Use `getChatGPTUser()` for optional signed-in UI.
-- Use `requireChatGPTUser(returnTo)` for server-rendered pages that should send
-  anonymous visitors through Sign in with ChatGPT.
-- Use `chatGPTSignInPath(returnTo)` and `chatGPTSignOutPath(returnTo)` for
-  browser links or actions.
-- Pass a same-origin relative `returnTo` path for the destination after sign-in
-  or sign-out. The helper validates and safely encodes it.
-- Mark protected pages with `export const dynamic = "force-dynamic"` because
-  they depend on per-request identity headers.
-
-Dispatch owns `/signin-with-chatgpt`, `/signout-with-chatgpt`, `/callback`, the
-OAuth cookies, and identity header injection. Do not implement app routes for
-those reserved paths. Routes that do not import and call the helper remain
-anonymous-compatible.
-
-SIWC establishes identity only; it does not prove workspace membership. Use the
-Sites hosting platform's access policy controls for workspace-wide restrictions,
-or enforce explicit server-side membership or allowlist checks.
-
-Use SIWC for account pages, user-specific dashboards, saved records, and write
-actions tied to the current ChatGPT user. Leave public content anonymous.
