March 2025 focused on stabilizing DevTools source-location reporting for nested CSS declarations in Stylo integrations. Implemented tracking of the first declaration within a nested block to accurately report the source location, ensuring DevTools and InspectorUtils.getRelativeRuleLine reflect correct rule positions across two repositories.

January 2025 monthly summary focused on gating anchor-center keyword visibility behind the feature flag to ensure devtools behavior mirrors feature availability across repositories. Implemented feature-flag gating in both DioxusLabs/stylo and servo/stylo, aligning keyword exposure with layout.css.anchor-positioning.enabled and preventing exposure when the feature is disabled. This improves accuracy of devtools results, reduces developer confusion, and strengthens feature-driven workflows.
