Jan 1, 2026Summary for 2026-01: Delivered targeted improvements to rendering reliability and user interaction in the effects-runtime, focusing on cross-platform compatibility and consistent visuals. Implemented font family validation optimization for simulator compatibility; unified rendering size units for rich text and sprite; added particle click event support for interactive removal flows. Fixed edge cases in rendering: text outline renders only when width > 0 and emoji handling corrected using Array.from to treat emojis as single characters. These changes reduce rendering errors, improve UX, and strengthen production stability.
