/* The furniture every screen puts around its content: the page header — icon,
 * title, subtitle, actions — and the block a view shows when it is still
 * reading, could not read, or read fine and there is nothing.
 *
 * In `shared/` because a data space's own documents need them too. The portal's
 * components import this file; a hand-written page links it from `/shared/`.
 * Colours chain to the published palette in `/shared/theme.css` for the same
 * reason the footer's do: `--primary` and its neighbours are the bundle's
 * tokens, and a page that never runs the bundle would otherwise get an
 * unresolved `var()`, which is an invalid declaration rather than a default.
