/* Crypto crime × BTC report (/research/crypto-crime-timeline/) on cw-system + cw-reading.

   its markup and script; only colours, type and spacing moved to cw tokens.
   One exception to "IKB is the only accent": the BTC price line stays orange, because the report
   text and its legend name it (橙线). #e0561f is 3.64:1 on paper; graphics need 3:1. */
