Subject: [PATCH] feat(ocr): allow re-running OCR when transcription blocks
 already exist
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a collapsible OCR trigger below the block list in edit mode.
Uses a <details> element so it's unobtrusive — the primary workflow
is editing existing blocks, but users can expand to re-run OCR with
a confirmation dialog that warns about replacing existing blocks.
