+# Evo2 SAE Feature Explorer (front-end)
+
+Interactive dashboard for Evo2 SAE features — feature atlas, sequence inspector, and
+generative steering.
+
+This directory is the **front-end only**. Its backend is the standalone
+[`evo2_sae_infer`](../evo2_sae_infer) engine — the viz is just a UI over its
+`serve` mode, so there is no model code here.
+
+```bash
+# 1. Backend: loads Evo2 + the SAE and serves the HTTP API on :8001
+../scripts/launch_inference.sh serve          # or: python -m evo2_sae_infer serve
+
+# 2. Front-end (this directory)
+npm install && npm run dev                     # Vite dev server
+```
+
+The Vite dev server proxies `/api` → `http://localhost:8001` (see `vite.config.js`);
+point it elsewhere with the `VITE_BACKEND` env var. Configure the backend (checkpoint,
+SAE, layer, feature annotations) via the env vars documented in `launch_inference.sh`.
