// Slice 4 Part 4 — the card while an update runs, while an app is held, and after an update that
// failed without a hold. Rendered through the REAL stacks template.
//
// THE TRAP THESE PIN: isOperationalState counts `restarting` as operational — that is how the
// 2026-09-01 spike saw a green Frissítés beside a crash loop. Both fixtures below are in
// StateRestarting on purpose, so a template that checked isOperational FIRST would render all three
// lifecycle buttons and fail here.
//
// COMPANION RED-PROOF (REPORT.md): move the `{{if .Updating}}…{{else if .HoldReason}}` branches below
// `isOperational` in stacks.html — the held and updating tests fail with the buttons present.
