/* ===========================================================================
   Samui Jetski Safari — visual mockup design system (LIGHT theme).
   Clean & white, tropical, sea, freedom, happy. Brand accents: cyan/sky,
   retro-sunset orange, magenta, tropical green — on airy white backgrounds.
   Class names are stable; semantic CSS variables drive the palette so the
   markup in app.js/admin.js adapts automatically.
