/* S2 test lab (#one-setting) + the benchmark reveal card (#first-test, inside it). v7, 12 Nov 2026.
   Dark surface, a trading-terminal card: tabs 1小时图 / 4小时图 / 日线图 switch the big number and the real
   equity line (tester-data.js). Colour: red only for the version that ends below RM10,000. The other two and
   "holding BTC" stay neutral: none of the three versions beats holding, so nothing here is green.
   Hidden-before-motion rules hang on html.ds-motion: no JS / reduced motion = final state. */
