+-- http/wsframe.wo — the RFC 6455 frame codec (iteration 24), pure
+-- functions over Text (net.read/net.write speak Text; a wo Text is
+-- binary-safe bytes). No fd, no actor — the reader owns a carry buffer
+-- exactly like internal/parse.wo's keep-alive carry: append what
+-- net.read returned, call ws_parse, act on the frame, keep `rest`.
+--
+-- v1 bounds, all deliberate (spec 2026-08-23): client frames MUST be
+-- masked (RFC), fragmentation is refused (kind -1 — answer a close),
+-- 64-bit payload lengths are refused, payloads cap at 1 MiB (the
+-- BODY_MAX doctrine). Binary frames parse fine; what an app does with
+-- them is its business (chat echoes).
+--
+-- Frame.kind: 0 = incomplete (feed more bytes), 1 = text, 2 = binary,
+-- 8 = close, 9 = ping, 10 = pong, 0 - 1 = protocol error (close the
+-- peer). kind mirrors the wire opcode for real frames.
