_ → + → △ → □ → _. The cursor builds up through the shapes while thinking, then collapses back to the waiting underscore. Watch the two side by side — the geometric build is your extension.
_ → caret → dot → _. Three forms, abstract.
One line → two (plus) → three (triangle) → four (square) → back. Counts up, then settles.
_ → + → △ → □ → _
Transparent, but a confident border + bold white so it reads finished, not disabled. Tap it — red on contact (action), then fades.
