The December 2025 MBR deck is built, with six slides, in the house format. The script ran cleanly on the first attempt and checked every figure against the two sources.

Deck: `output/IS_MBR_2025-12.pptx`

The script printed: "December 2025 deck: 6 slides, 55 figures, every one from a source. Wrote output/IS_MBR_2025-12.pptx and output/deck.json"

I generated `output/slide-map.json` with a small helper script, `output/make_map.py`, so every figure was copied from the sources and none were typed. You can delete the helper.
