Schematic SVG preview

Compact schematic render of the board — a few kB of plain SVG text, directly consumable by multimodal LLMs as an image. Shows texts as labeled rectangles, strokes as polylines with exact world coordinates, and images as placeholder boxes (or tiny thumbnails if provided). Mermaid blocks currently render as a [mermaid diagram] placeholder — fetch /json/{id} for the raw source. AI-authored items are rendered with a purple border so the viewer can tell apart AI and human contributions.
