Package	What it does
`dec`	18-digit fixed-point decimal (LegacyDec precision), half-up rounding, tick floor/ceil, fuzz test
`book`	L2 book, validation, mid/spread/depth, taker walk, O(n) level diff, exchange tick and min-notional checks
`fba`	Frequent batch auction: stage 1 market orders, stage 2 limit orders with uniform clearing price; tests are the two worked examples in the Injective API docs
`client`	LCD client: hedged requests across 4 public endpoints, seq guard against lagging nodes, per-endpoint health
`cmd/wasm`	Browser entry: exposes the packages to JS as Promises (net/http runs on fetch)
`cmd/injbook`	CLI: live book + taker cost for any market
`cmd/bookd`	REST + WebSocket server: one poller per market fans out snapshots and diffs to every client
