/* ============================================================
   ALLOY CINEMATIC v2 — Investor layer
   Owner: SA-7 (Investor toggle + per-section ground-truth expand)
   ------------------------------------------------------------
   Tokens come from cinematic-v2.css :root (do NOT edit that file).
   Contract:
     - Investor mode default OFF. Adds density, never removes the
       default cinematic SOP story (copy + mermaid stay visible).
     - body.investor-mode is the single global switch.
     - Per-section "Ground truth" panels are collapsible at ALL
       times (independent of global mode); investor-only blocks
       (parity/metric badges + honest-limits) appear only when
       body.investor-mode is set.
   All classes are prefixed .ig- (investor-ground) or reuse the
   already-scoped .sop-embed__* names so nothing leaks.
