/* ==========================================================================
   Obol Portal — Customer-facing design system
   Direction: "Editorial monochrome."
   Warm paper background, jet-black ink, stone tints. No hue-based accent —
   the "accent" IS the black: buttons are black, links are black-underlined,
   emphasis is achieved through weight, density, and inversion. Feels like a
   well-set broadsheet or a receipt from a very serious Scandinavian bank.
   All rules are scoped to `.portal-layout` so the admin UI is unaffected.
