Detailed Description

Strict UTF-8 validation (RFC 3629), one shared copy.

Several protocols must reject non-UTF-8 input: WebSocket TEXT frames (RFC 6455 8.1, fail with close 1007) and MQTT strings (MQTT 1.5.3). Both use this single validator rather than each rolling its own. Header-only inline, like the other shared primitives - zero link cost when unused.
