Introducing Fern Replay 🔁: buildwithfern.com/post/fern-repl…

Until now, customizing a Fern-generated SDK was file-level: let the generator overwrite your edits, or .fernignore the file and own it yourself forever. Replay is the line-level answer. After each regeneration, Replay detects your edits and ships the result as a single PR for review.

Works across every SDK language. Generally available and already running in production at @Frame_io , @auth0, and @smallest_AI
