   Design language: Japanese indigo (藍染 aizome) meeting a trading terminal.
   The palette is built from three real Japanese pigments — aizome indigo,
   shu-iro vermilion (the colour of a torii gate), and kin gold — pushed into a
   near-black ground so the cyan data-glow reads as instrumentation rather than
   decoration. Vermilion appears perhaps six times in the whole page: it marks
   thresholds, the way a torii does, and loses that meaning the moment it is
   used for ordinary emphasis.

   MOBILE FIRST. Every base rule targets a 360px phone. Enhancements are added
   upward through min-width queries — never stripped back down.
