Done! I've built the FY2025 revenue bridge for InterStationary and written the commentary note.

**Summary:**
- InterStationary's revenue was essentially flat, declining just ($5K) year-over-year to $11.2M
- Four customer losses totaling ($1.3M) were the largest headwind, with Fenwick Legal ($686K) and Birchway Foods ($503K) departing
- These losses were mostly offset by $1.2M in upsell growth across 23 customers and $463K from 6 new customers
- Top upsell drivers: Harbor Freight Partners ($148K), Ember Analytics ($136K), and Alder Logistics ($126K)

Both the detailed bridge data (`bridge.json`) and one-page note (`bridge-note.md`) are in `output/`.
