4/ One thing I liked is how OJO treats skills.

Design is extremely detail-driven.

The strategy has to be right, but the scale of a product is often decided in the details:

interaction paths, visual hierarchy, layout, motion, micro-interactions.
OJO has an ecosystem ambition here.
It comes with many skills, and users can upload their own.
That matters because taste should not be frozen inside. It should evolve with the market, and with every talented builder using the system.
In my case, I used a GSAP motion skill to give the page more visual impact.
