/* Settings sheet — the operator controls (js/settings.js).
 *
 * Leans entirely on base.css for tokens and for .btn / .surface-card /
 * .sheet / .section-label. What is defined here is only what this screen adds:
 * the gear in the Feed header, the status rows, the verdict lines, the commit
 * log and the restart panel.
 *
 * Target is a 390x844 iPhone in standalone mode. Two rules drove the layout:
 * every button is at least 44px and full width (this screen is used one-handed,
 * often in a hurry, and a mis-tap here restarts the server), and every code-ish
 * string scrolls inside its own box rather than widening the sheet — a commit
 * subject or an npm error is arbitrarily long and must never cause a
 * horizontal scroll of the whole page.
