/*
  Kanzlei Dr. Keller — Familienrecht, Hamburg

  Design palette drawn from warm Hamburg interiors:
  aged oak panelling, linen-white walls, sandstone mouldings,
  and the quiet sage greens along the Außenalster.
  Typography pairs a warm serif (Georgia) for headings with
  a neutral system sans-serif for body text, tuned for generous
  line-height and deliberate spacing.
