   SNV-Septik — design tokens
   Concept: geological cross-section / survey field notebook.
   Palette: cool water-engineering blue as the dominant accent
   (buttons, links, eyebrows, groundwater) with a deliberate
   second role for green — sequence markers and the equipment/
   earth texture, matching the real green tanks in site photos.
   The two accents never compete for the same job.
