 * stage that can fail, and whoever inherits this can change a colour without
 * first reconstructing a toolchain.
 *
 * The visual language follows LinkedIn: a warm grey page, white cards with soft
 * borders, pill-shaped buttons and a single confident blue. It is chosen for a
 * reason beyond taste. The only person who uses this screen is not technical,
 * and a layout she already recognises from somewhere else costs her nothing to
