/* MuScriptor Studio — showcase site.
   Colours come from the app (Sources/MuScriptorStudio/StudioPalette.swift): the dark theme reuses
   them as they are, the light theme takes the app's own light values and darkens mint and peach
   until text passes 4.5:1. Components only use the tokens below. */
