The December 2025 review deck is built: `output/IS_MBR_2025-12.pptx`. It has six slides in the house template. The script reported all 56 figures as matching the two source files, and it wrote `output/deck.json`. I didn't open the .pptx to check how it looks.

The slides are:
1. **Title:** December 2025 Monthly Business Review, InterStationary.
2. **Headline:** revenue $827K against a $824K budget. Operating income $8K against $13K. Gross margin 26.1% against 26.8%.
3. **P&L vs budget:** five rows, from revenue through operating income.
4. **KPI scorecard:** all eight KPIs, four on target and four off.
5. **Drivers:** Other operating and Cost of goods sold, each ($6K) in the month. Technology $4K favourable. Revenue ($362K) for the year to date.
6. **Watch list:** Days sales outstanding and On-time delivery percent, each off target for 3 months. Active customers for 2 months and Inventory turns for 1.

I wrote the slide map by hand, copying each figure from the two source files. I also saved it as `output/slide-map.json`.
