+Remove `better-auth` from `peerDependencies`. Optional peers still led npm to resolve Better Auth’s peer graph (including `@sveltejs/kit` / Vite), causing `ERESOLVE` for apps that do not use Better Auth ([#299](https://github.com/HugoRCD/evlog/issues/299)). Users of `evlog/better-auth` should keep `better-auth` as a direct dependency (see docs).

 `evlog/better-auth` turns anonymous wide events into identified ones. Every request automatically includes who made it — no manual `log.set({ user })` needed.
 
+## Prerequisites
+
+Use [Better Auth](https://better-auth.com/) as a **direct dependency** in your app (`npm i better-auth`, `pnpm add better-auth`, `bun add better-auth`, etc.). `evlog` does not bundle Better Auth. The integration is tested against Better Auth `>=1.6.9` (same major as [the playground](https://github.com/HugoRCD/evlog/tree/main/apps/playground)).
