/* ============================================================
   simulator.css - the shared Ledger layer for both backtesters

   Loaded AFTER turtle-simulator.css / ma-simulator.css, which stay
   in place for anything page-specific. Every class here is one the
   pages already emit or one of their scripts sets, so no markup and
   no JS had to change: the two files disagree on a handful of rules
   and this settles both the same way.

   What it does: takes the cards off. A backtester is a sheet you
   fill in and a report you read, so the controls are underlined
   rather than boxed, the readings sit on hairlines, and the only
   filled surfaces left are the ones that depict something - a chart,
   a tooltip, the run button.
