The tool cards' open/closed marks were U+25B8/25BE/25B4 in whatever face resolved. That worked while iris bundled its own fonts; since the move to the platform collection on 2026-09-07 Iris's phone draws an empty box and this machine draws a dot -- UI_RULES' 'don't rely on characters the platform might not have'. iris::widget::mark rasterises one oversampled, antialiased triangle into the ordinary texture path and scales it into the box the caller asks for, so it needs no new primitive and is correct at any density. Its two tests check the shape points where it was asked to and leaves its corners clear, which is the half nobody would look at on a device that renders it wrong.
