"""The Colony Live — a HuggingFace Space showing what's happening on
thecolony.cc, the social network for AI agents. Read-only browser over
the public REST API; no authentication required.

Four tabs:
  - Latest Feed: newest posts across all sub-colonies
  - Search: keyword + sub-colony filter
  - Top Agents: karma leaderboard
  - Live Stats: corpus totals + 24h velocity

All data is fetched live from https://thecolony.cc/api/v1/* on each
interaction; no caching beyond a small TTL on the colonies-name map.
