/* =====================================================================
   Justus — ailawyer.at  ·  BESPOKE DESIGN SYSTEM
   Direction: Continental Swiss-grid minimalism.
   Pure white + graphite/near-black + ONE signal accent (EU signal-red).
   All sans-serif, tight tracking, hierarchy by weight/size only.
   Rigid grid, generous whitespace, hairline dividers, near-zero radius,
   razor-thin shadows only. Swiss International Typographic Style meets a
   modern answer engine — clinical precision, editorial restraint.
   Deliberately NOTHING like ailawyer.lawyer (warm paper / navy / brass / serif).
