Hide & Seek 2.0 — v1.5.0 (scenarios + live demo)

Hide & Seek 2.0 -- v1.5.0

▶ Live demo (no install): https://gefaa.github.io/hide-and-seek-2/

Viewer

• Six named scenarios you can switch in your browser — Synthetic Showcase,
  Fort Building, Ramp Use, Running & Chasing, Door Blocking, Sensory Deception —
  each a short curated clip that isolates one emergent behaviour.
• In-viewer scenario picker + shareable #scenario=<id> deep links, with
  a per-scenario caption/description.
• Agents now have little faces, and on-screen event cues announce
  "Seekers released", "Door opened", "Wall broken", "Decoy activated" and
  "Hider spotted".

Project

• Live demo on GitHub Pages (auto-deployed from viz/web) and CI
  (byte-compile + JAX-free config tests) — see the README badges.
• New CHANGELOG.md and CONTRIBUTING.md; the curated scenario
  trajectories + manifest.json now ship with the repo.

Built on the v1.0.x clean, OpenAI Emergent Tool Use-style viewer. This remains
a research scaffold; the JAX training paths still require a JAX/GPU environment.
