/**
 * A ProgressIndicator.
 *
 * `determinate` says whether the value means anything, and `circular` picks the form.
 * Everything else, the thickness, the colours, whether the ends are round or square and how
 * fast an indeterminate sweep travels, belongs to
 * [dev.darkpyonix.composerust.design.ComponentRules.controlWidgets]. How fast something moves is
 * motion, and motion is the design system's decision rather than a Host property.
