/* ============================================================================
   Neptune: site styles
   ----------------------------------------------------------------------------
   Palette is lifted from the app's default "Deep Instrument" theme
   (Neptune/Theme/AppTheme.swift) so the site reads as the same product.
   Page chrome is set in Geist (self-hosted, OFL). The phone mockups keep
   the system font on purpose: the app itself renders in SF Pro.

   Motion rules: every animation is either load choreography, a scroll
   reveal, or feedback on interaction, and all of it collapses to static
   under prefers-reduced-motion (bottom of the chrome section).
