/* ════════════════ BACKTEST — institution-grade precision layer (loaded LAST) ════════════════ */
/* Scope: the backtest float content (#btOut · #btParams · #btLogBody) + the terminal BT panel (#termBT).
   Geometry scale: metric cards / inputs / trade-log = 8px radius · one hairline var(--line) border.
   Honesty/color law preserved: numbers are tabular-nums (no digit jitter); green/red = P&L / direction
   ONLY; amber var(--pcac) = chrome. This layer is additive (loaded after chart-plot.css) — it styles the
   pcbt-* classes the backtest markup now carries; it does not relocate or weaken any existing rule. */
