/* The design system every surface shares.
 *
 * One stylesheet rather than one per page, because the five surfaces are
 * one product seen by five people and a tenant portal that looks like a
 * different company from the operator console is a tell.
 *
 * Instrument panel, not dashboard: a fixed summary band above stacked
 * panels, each panel a plain table of one thing. Nothing is a card unless
 * it is a node or a job. No gradients, no shadows that imply depth nothing
 * has, no colour that is not carrying information.
