   Two modes, one page. The accent follows the mode: BitcoinIII orange for
   cPPLNS (a coinbase shared out), cyan for SOLO (one address, one block).
   Data is set in a monospace face because everything a miner actually
   handles here - addresses, ports, d=DIFF, hashrates - is monospaced anyway.
   Source is plain ASCII; special characters are written as escapes. */
