Every tool on the site, arranged around its area the way a mind map branches from a central idea — except this one drifts, breathes, and pushes gently away from your cursor.
No two visits look quite the same — the bubbles are always mid-drift — and it's the one page that shows the whole shape of the site's rules of thumb at a glance, like a print left by the hand behind it.
The filter bar above dims everything except matches as you type, or use the area chips to isolate one discipline. Prefer a flat list?
