The December 2025 MBR deck is built at `output/IS_MBR_2025-12.pptx`. It has six slides in the house format. I didn't open the .pptx to check how it looks.

The script printed: "December 2025 deck: 6 slides, 59 figures, every one from a source. Wrote output/IS_MBR_2025-12.pptx and output/deck.json"

I also wrote `output/slide-map.json`, the file the script builds the deck from.
