The venues we count, and what Other holds

Counted separately: Polymarket, Kalshi, Polymarket US, Crypto.com, Predict and Limitless. **Other** holds the venues the source reports as one group, plus Novig: Opinion, Hyperliquid, Novig, Myriad, Overtime, Gemini and ForecastEx. Splitting Opinion or Hyperliquid out would need their own queries, which we may add later. Adding a venue is a configuration change, not a code change: when a venue appears separately in the source, one row maps it to its own line on the page.
