25/**
26 * The app's standard top bar: a title (with optional subtitle), an optional up/back button, an
27 * optional inline loading indicator, and trailing actions. Extracted so the many plain
28 * back-title-actions screens share one implementation instead of hand-rolling a [TopAppBar] each.
29 * Screens with a bespoke title (dropdown server switcher, clickable model picker) keep their own bar.
