/**
 * `<NavHeader>` — HeroUI-themed header bar for `@sigx/lynx-navigation`.
 *
 * Pairs with `<Stack>`:
 *
 * ```tsx
 * <Stack initialRoute="home"><NavHeader /></Stack>
 * ```
 *
 * Reads the focused screen's options + slot fills via `useScreenChrome()` and
 * applies hero theming (base-200 surface, bottom separator, centred title).
 * Icons themed through `<Icon variant>` — resolved by `<ThemeProvider>`'s
 * (zero's) icon-color resolver to the active hero palette hex.
 *
 * The navigation package's own `<Header />` is headless; this is the
 * batteries-included variant for hero consumers.
