/* ===========================================================================
   iOS System Sounds

   Built on Nocturne, the design system bound to the Claude Design project.
   Nocturne is dark-native, so the dark theme is its own tokens; the light
   theme is mirrored out of its neutral and accent ramps rather than invented,
   which is why the accent darkens to accent-700 on paper and the ground is a
   cool neutral-100 instead of the warm stock it used to be.

   Nocturne's signatures, and where they land:
     · rules fade to transparent at both ends — section rules and every row
     · 8px / 10px / 14px radii, never square
     · outline buttons that tint on hover, never filled slabs
     · 11px uppercase kickers with wide tracking, in the accent
     · a blurred, translucent header and transport over a gradient ground

   The data colours do not follow the system: green means a sound still ships,
   rust means it has oxidised out, and those hold their meaning in both themes.
