/* =====================================================================
   Luma Biohacking Resort — Living Lab v02
   Re-accent (per Design Pack §6 C1): NOT a "lab" as hero. A premium
   residence where a full-floor longevity clinic is a built-in privilege.
   Data-precise, clinical-calm, confident. Cold bio-light diagnostic accent,
   mono tabular numerals — measured, not marketed.
   Fonts: Geologica (technical grotesk sans, Cyrillic) + JetBrains Mono (numerals, Cyrillic).
   NO serif (deliberately distinct from Cliff Sanctuary / Editorial).
   Prod sans -> TT Hoves Pro (one-line stack swap).
