/* =================================================================
   ClientFlow CRM — Stylesheet
   =================================================================
   DESIGN TOKENS
   Every color, font and spacing value the app uses is declared
   once at the top as a CSS "custom property" (a variable, written
   --like-this). Every other rule below reads from these variables
   instead of repeating hex codes everywhere. Change a value here
   and it updates the whole app — that's the entire point of
   having tokens instead of scattering colors through the file.

   Palette:
     --ink       near-black text, cool blue-grey tint
     --paper     the page background (cool light grey, not white)
     --surface   card / panel background
     --primary   brand blue — buttons, links, active nav, focus
     --accent    emerald green — money, conversions, success
     --warn      burnt amber — medium/high priority, warnings
     --danger    red — delete actions, "Lost" status, errors

   Type:
     --font-display  "Space Grotesk" — headings, big numbers
     --font-body     "Inter" — body text, forms, table rows
