/**
 * Mermaid whiteboard post-processing.
 *
 * After lark-cli creates whiteboard blocks from mermaid fences, this module
 * patches connector caption background colors via the lark-cli whiteboard
 * API (v1.0.8+):
 *
 * Flow:
 *   1. Query raw DSL via whiteboard +query --output_as raw
 *   2. Patch caption background colors in DSL
 *   3. Re-upload patched DSL via +whiteboard-update --input_format raw
 *
 * The whiteboard is already created by lark-cli during document creation
 * (from the mermaid fence). We only need to patch the caption styling.
 * Replaces the old whiteboard-cli external dependency approach.

 * fences appeared in the uploaded markdown. Silently skips boards whose mermaid
