/* =============================================================================
   VitaNouvelle LifeScience — house design system (redesign, 2026-10)
   Renamed from VitaLita Bioscience on 2026-10-27. The house keeps its vita
   green; since 2026-10-28 it carries three accents: gold (Halo and the HydroSure
   label) and the sage and mist of the founders' first emblem.
   The house speaks in a light serif on pearl; the product worlds (HydroSure
   first) show through framed windows and never color the house itself.
   Type: Boska (display, 300/400 + italic) · Switzer (text + UI).
   Motion follows Apple's fluid-interface rules: instant press feedback,
   critically damped easing, transform/opacity only, reduced-motion aware.
