// Three states, one column: done, failed, and still running. The failure is
// coloured by a badge and never by a text colour on the row, so it survives
// every style and stays readable to anyone who cannot see the hue.
//
// The five rows are written out rather than mapped. Each state carries
// something different (a badge here, a spinner there), so a data driven version
// needs a switch in the row body and reads worse than the markup it replaces.
//
// The spinner sits inside the icon slot, which the primitive hides from
// assistive tech together with its subtree, so its own status role never
// reaches the accessibility tree. The row states its progress in text instead,
// and keeps role="status" for the app that swaps this line out at runtime.
