The Abonnemang tab gets a quiet decorative masthead: the marketing site's
halftone Stockholm skyline as a wide banner strip on the frame tint,
waterline pinned to the strip's bottom edge (same physics as the
onboarding backdrop). Shown in every billing state; purely decorative.
The API tab's "Anslut MCP-klient" group gets a works-with strip using the
site's monochrome halftone Claude and OpenAI marks (copied into
public/illustrations and registered in the shared manifest), with a
bilingual caption.
