/**
 * Sharing a space, in the shape of Keith's ⌘K design (2026-10-06): a popover rather than a dimmed
 * dialog, opened from the space's app menu and held under its pill, the people with access at the
 * top, and every change applied as it is made.
 *
 * Its colours are design.css's `--ds-*` tokens, the same as the command menu's, each falling back to
 * the space's own for a page that has not loaded design.css. Still a `<dialog>` opened modally, for
 * the focus trap and Escape; the backdrop is clear and closes it, the way a popover does.
