/* Compact page header (ADR-0072 amendment 2026-10-06): shared by every page that renders <PageHeader Compact>.
   Global (not scoped) on purpose: the row, the panels and the chips are filled by the PAGE through slots, so their markup
   carries the page's scope id, not the component's (skill blazor-scoped-css-class-on-child-component-needs-deep).
   Visual language = the `.pl-*` panels of «Risorse e commesse» (people-load-compact mock), under the neutral prefix `ph-`.
   One breakpoint: 600 px, written as a plain @media (max-width: 599.98px) — never MudHidden (skill mudhidden-breakpoint-exact-not-andup).
   Touch targets are 48 px under the breakpoint, 36 px above it. */
