2026-01 Monthly Summary — Servo Stylo. Focused on strengthening background serialization correctness in the styling system. Delivered a feature to auto-detect when both width and height are auto for background sizes, and fixed the serialization order of CSS background properties so the background color is serialized last. These changes improve rendering consistency, reduce edge-case regressions, and stabilize background-related serialization across the styling pipeline.

June 2025: Delivered a user-facing Screenshot Save Location Preference in mozilla/gecko-dev, enabling saving screenshots to the OS screenshots directory, Downloads, a custom directory, or other OS-specific locations.
