/*
  NORDVISTE WOHNUNGEN GMBH — Design System
  Design Philosophy: "Berliner Editorial Premium"
  - Near-black (#0f0f0f) base with pure white text and warm gold accents (#c9a96e)
  - DM Serif Display (headings) + Instrument Sans (body) — sharp contrast
  - Full-bleed image sections, oversized typography, editorial whitespace
  - NO grid cards, NO icon-rows, NO colored sidebars from previous sites
  - Mobile-first: every section designed for 390px first, then scaled up
  - Signature: large section numbers, thin rule lines, staggered text blocks
