-### Nexus Portal Integration
-
-This repo now ships the Beacon-side artifacts needed for Nexus embedding:
-- `portals.json` — Beacon portal registry entry pointing at `./index.html?portal=nexus-beacon`
-- `nexus-panel-preview.html` — local iframe harness for validating the portal panel experience
-- `js/portal.js` — portal-mode detection plus portal-scoped save persistence
-
-Use `nexus-panel-preview.html` to verify the game in an iframe before wiring the same URL into the live Nexus atlas.
