//! Subtitle OCR subsystem for bitmap subtitle streams.
//!
//! This module owns end-to-end OCR conversion used by the transcoder path:
//! discover bitmap subtitle streams, run OCR, and remux text subtitles.
//! It is the integration layer over `engine`, `ocr_pipeline`, `text_processing`,
//! `text_render`, `language`, and `muxing`.
