## Description

* Set the versioning, deprecation, and breaking-change policy for a library 60+ repositories depend on, and define the migration architecture that moves them across.

 * Define the build, release, and testing strategy, including automated visual regression and the token pipeline that keeps design and code from drifting.

 * Architect the library to be correctly consumable by AI coding agents, so generated frontend code is compliant and accessible by default rather than by manual review.

 * Define the accessibility standard the platform builds against, with conformance validated in the pipeline rather than caught downstream, and support the compliance obligations our customers require.

 * Own reliability and incident response across the new library and the legacy libraries, and build the severity and escalation model the team does not have today.

 * Resolve complex, cross-organizational technical problems through deep technical expertise, collaboration, and hands-on implementation.

 * Drive frontend engineering standards across teams through design and code reviews, patterns, documented standards, and coaching, and align technical execution with product strategy and delivery commitments.
