## Notes
- Token check uses the free public Solana RPC and DexScreener; results can be incomplete when they rate-limit. Not financial advice.
- Ticker check only sees tokens DexScreener has indexed plus the JestSprout gallery; tickers are not unique on Solana.
- Logos are deterministic SVGs: same inputs, same image, safe to cache.
