 /** tts_bridge.js — Persistent Node.js bridge for aquestalk.js TTS synthesis.
 
-Protocol (via stdin/stdout):
-  - On startup, prints "READY" to stdout.
-  - Reads lines from stdin in format:  INPUT_PATH|OUTPUT_PATH
-  - Reads kana text from INPUT_PATH, synthesizes WAV, writes to OUTPUT_PATH.
-  - Prints "OK:OUTPUT_PATH" on success, "ERR:message" on failure.
-  - Exits when stdin is closed.
-
-Usage:
-  node tts_bridge.js --voice f1 --speed 100
+Converts English/romaji to katakana via wanakana before synthesis.
