Why true gates are the only rounded elements in the UI

HIIE's interface follows a strict design law: the whole UI is non-rounded, with a corner radius of zero. Rounding is reserved exclusively for one thing — a true gate.

What a true gate is

A true gate is a hard, blocking human decision: a moment where an agent cannot proceed until you make a call. In HIIE this is expressed through the Human Input Popup (HIP) system. When Camelia needs you to approve a hard decision, she raises an approval that opens as a rounded true-gate popup.

Why rounding is the signal

Because every other surface in the product is square-cornered, rounded corners become an unmistakable visual cue. The instant something is rounded, you know it's a true gate — a blocking decision that requires your judgment, not just another panel or control. The design intentionally makes these moments stand out so they're never mistaken for routine UI.

Which HIPs are true gates

The approval HIPs are the true gates: approving a document deletion, approving an external integration write, or approving a capacity top-up. Each is a hard, blocking decision, so each is presented with the reserved rounded treatment.

The takeaway

If you see a rounded element in HIIE, treat it as significant. It means the system has paused and handed you a decision it cannot make on its own. Everything else — your documents, designs, flows, and chat — stays square, keeping the visual language clean and making genuine gates impossible to overlook.
