/* ============================================================================
   KTS master dashboard — app.css

   THE RULE (§6): every colour in this app comes from a token. A hardcoded hex
   anywhere outside the four token blocks below is a defect. Data-driven
   inline styles (status colours) reference the tokens through var().

   Token blocks:
     1. :root[data-theme="dark"]   — the default
     2. :root[data-theme="light"]
     3. .wall                      — the status wall, which stays DARK in both
                                     themes. It is the signature element, and
                                     glowing tiles on a dark panel read
                                     correctly inside a light UI.
     4. @media print              — paper is white and ink is black in both
                                     themes, the wall included.
