/* =========================================================================
   Nomien — landing page styles
   Visual language: "The Pristine Curator" (ADR-008, 2026-06-30 Nomien refresh)

   Brand decisions live in :root below. Re-theming the whole site is a token
   edit — component rules reference the tokens, never raw brand values.

   Hard rules enforced here:
   - Tonal separation only. Areas separate via whitespace and surface tone
     (#FFFFFF -> #F9F9F9 -> #EDE8DA hover). No borders/hairlines for structure.
   - Shadows appear only on elements that genuinely float.
   - Signature red (--bn-primary) is precious: CTAs + critical data only.
   - Oswald for hero/section titles only. Schibsted Grotesk everywhere else.
   - Focus ring is near-black (--bn-text), never red.
