/* ==========================================================================
   TCC Utility Portal — visual system

   The reference is a precision instrument panel, not a SaaS dashboard: a deep
   near-black field, thin luminous rules, and data that appears to sit *above*
   the surface rather than inside boxes. Every number is set in a mono face with
   tabular figures so columns lock to a grid. Each utility owns one hue and
   keeps it everywhere — chip, line, glow, axis — so colour carries meaning
   instead of decoration. Light mode is the same system inverted for anyone who
   spends the day in spreadsheets.
