03 THE AI THAT EXPLAINS ✦

It explains. It never decides.

An AI button on every item tells you what that folder contains and why it has that color — in your language, with cost and duration visible. The verdict always stays with the rules.

This folder is the browser's “storage room”: it keeps copies of pages you've visited so they reopen faster. It rebuilds itself whenever needed, so clearing it loses nothing important — you just get the space back.
