    List Input Crash Fix

    Brand Kit Core

    ✨ What''s Improved

    The Problem

    The shared ListInputCard component called .trim() on its input value without a nullish check. When the value was undefined (e.g. on first render of certain cards), it threw TypeError: Cannot read properties of undefined (reading ''trim'') and triggered a blank screen.

    The Fix

    Added a nullish fallback ((value ?? '''').trim()) so undefined values are safely treated as empty strings.

    Impact

    This fix applies to every tag/list editor across Personality, Storytelling, Governance, and Expression cards.
