/* ==========================================================================
   Viper Hold — design system
   --------------------------------------------------------------------------
   Concept: "Coil & Strike". Dark panels are the coil — patient, data-dense,
   where the thinking happens. Light sections are the strike — bright, plain,
   decisive. A single cold-blooded ice-blue thread runs through both as the
   brand mark, rules, numerals and checkmarks. The conversion button is that
   same thread at full strength: a filled ice pill, one per view, never two.
   Red appears only when something is wrong (invalid fields, failed sends).

   Hand-written. No preprocessor, no build step, no framework.
