Summary

React/Vite feature-explorer dashboard for Evo2 SAE features — three tabs: feature
atlas, sequence inspector, and generative steering. Front-end only; its
backend is the standalone evo2_sae_infer serve engine (#1603).

That backend is a runtime dependency (a separate process the dashboard calls via the
Vite /api:8001 proxy), not a code dependency — so this PR's diff is purely the
feature_explorer/ front-end and the two PRs are independent (merge in any order).

Refactors included here

  • Deleted the 686-line duplicate steering_server.py — the dashboard now uses the
    shared evo2_sae_infer engine (evo2 SAE inference engine + CLI (encode / batch / serve) #1603) instead of re-implementing model/SAE loading + endpoints.
  • Lifted the static styles object out of App.jsx into src/styles.js.
  • Removed dead viewport-animation code (zoomToPoint/resetViewport + their easing
    helpers, all unreferenced): App.jsx 1,634 → 1,352.
  • Added a README documenting the front-end / backend split.

feature_explorer/ net: 4,905 → 4,123 lines.

Note

The React build was not verified in the authoring environment — please run
npm run build + a visual check (and an evo2_sae_infer serve smoke) before marking ready.

WIP safety checkpoint. Live Evo2-1B + C13 SAE backend (steering_server.py:
/health, /features, /annotate, /generate) + a 3-tab React app (Feature
atlas, Generative steering, Sequence inspector). Multi-feature additive
clamp-after-prompt steering; by-name feature picker; editable phylo tag.

…er serve

The dashboard carried its own 686-line steering_server.py that re-implemented
Evo2 + SAE loading, the forward pass, and the /health,/features,/annotate,/generate
endpoints — all of which now live in the standalone evo2_sae_infer engine. Delete
it; the front-end already reaches :8001 via the Vite /api proxy, so it now consumes
`evo2_sae_infer serve` (whose endpoint set + response fields are a superset). Add a
README documenting the front-end / backend split.

Move the 164-line static `styles` object into src/styles.js. App.jsx drops
1634 -> 1470 lines and styling is isolated. Pure move — module-level static
object used as styles.*, no behavior change.

zoomToPoint + resetViewport (two fly-to / zoom-out useCallback animations) and the
easeOutQuart/easeInOutCubic/easeInOutQuad helpers they used were declared but never
referenced anywhere (each occurs only at its own declaration). Removing them drops
App.jsx 1470 -> 1352. No behavior change.
