class UI::ActivityRing

Overview

A circular activity ring rendered as a shared fallback surface.

The primitive stays intentionally modest: a determinate value range, optional supporting copy, and a composed ring stage built from Canvas arc operations plus existing stack/label views. Native bridges can come later without changing the public shared API.

Defined in:

ui/views/activity_ring.cr
