Hi @moshiur01, thanks for the contribution — dissolving typed text into particles is a fun idea.

We've decided not to move forward with this one. It's a curation call, not a code-quality one:

1. More demo than component. The styling is baked in (text-5xl, rounded-2xl, fixed padding), so it doesn't slot into a real form without fighting the defaults.
2. Heavy for what it does. It adds GSAP + MorphSVG as a second animation engine alongside motion, which is a lot to pull in for a single input.

Really appreciate the time you put into this. Thank you!
