+Ultra-low-latency binary protocol for HFT:
+- Zero-copy order placement/cancellation
+- Binary wire format (64-byte fixed orders)
+- Sub-100μs round-trip latency
+- Zero allocations on hot path
+
+**Wire Protocol:**
+```
+Order (64 bytes):
+  [0:8]   symbol (8 bytes, null-padded)
+  [8:16]  order_id (uint64, big-endian)
+  [16:24] price (float64, IEEE 754)
+  [24:32] size (float64, IEEE 754)
+  [32]    side (uint8: 0=buy, 1=sell)
+  [33]    order_type (uint8: 0=limit, 1=market)
+  [34:36] flags (uint16: post-only, reduce-only, STP)
+  [36:44] timestamp (uint64, unix nanos)
+  [44:60] user_id (16 bytes)
+  [60:64] padding
+
+Quote (24 bytes):
+  [0:8]   price (float64)
+  [8:16]  size (float64)
+  [16:20] count (uint32)

+BenchmarkZAPOrderPlacement    ~42μs/op    5.7KB/op    24 allocs
+BenchmarkZAPBestBid           ~48μs/op    5.7KB/op    18 allocs
+BenchmarkZAPRoundTrip         ~44μs/op    4.9KB/op    10 allocs
+```
+
+**Usage:**
+```go
+// Server

+
+// Client
+client, _ := rpc.Dial(ctx, "localhost:9000")
