How this architecture fixes your issue

- Both NIFTY and SENSEX publish into dedicated index-specific session keys.
- The AI analysis page reads shared in-memory state, not generic latest_df only.
- Generic latest_df is used only as guarded compatibility fallback.
- Same core fetch/render logic is reused for both indices.
- Each index has its own last keys, snapshot buffer, latest spot, pcr, and OHLC.
