Just finished making the Keepsake letter template. The letter experience opens with an interactive envelope scene built using 3D CSS transforms. Like other templates, users can also customize their letters in real time using client-side image carousels and alternate year pickers.

I have also made the AI rewrite feature functional. I also added a 150 word limit and a precise system prompt to optimize token usage. There are some bugs regarding the UI in the mobile view. I will fix those soon
