 * Two stacked rows — title row (back arrow + centred title) and an
 * optional guidance line below.  Lives in the SDK so every capture
 * surface gets identical chrome without re-implementing safe-area
 * handling, accessibility labels, and contrast on a black preview.
 *
 * Theming:
 *   The host has its own theme system; rather than coupling the SDK
 *   to it, the component exposes a small set of color props
 *   (defaulted to white-on-black for visibility against the camera
 *   preview).  Hosts that want to override pass `colors`.
