/* ==========================================================================
   Blockchain theme for the autosurf script ("Ledger light")
   Same light palette as the solar theme (white, leaf green, sky blue, sun
   orange) re-cut for an ad network that runs on-chain: isometric blocks,
   node lattices, mono hashes. Solar power stays as one small accent (the sun).
   Layout concept: white "block" surfaces on a faint isometric lattice; green
   for actions and confirmed blocks, blue for the chain and information,
   orange only for the sun, warnings and money due.
   Uses the SAME class names as design/assets/css/theme.css, so the PHP
   templates work with either theme; blockchain-only extras are at the end.
   No framework. ~24 KB unminified. Fonts: see README (self-host in production).
