/* =============================================================
   ZARAS — Operating-shapes card · operating-shapes-card.v1.css

   SHARED card-intrinsic CSS for the operating-shapes artifact (amber
   trade-rhythm lanes converging into one teal operating record).
   Loaded by BOTH home §03 (index.html) and the industries hero
   (industries.html). Extracted verbatim from home-industries.v1.css;
   replaces the duplicate copy that lived in industries-hero-card.v1.css.

   Scoped to the card's own .zi-* classes only — NO .zi section ancestor,
   NO body[data-page]/.hero scope — so each context frames it freely.

   PER-CONTEXT (deliberately NOT here): the card<->stack breakpoint and
   the show/hide strategy. Home swaps card->stack at <=760px (home-
   industries.v2.css); the industries hero hides the whole artifact at
   <=900px (industries.html inline). The stack APPEARANCE is here at
   base (display:none until a context shows it); only the display toggle
   is per-context.

   Namespace: zi-*  (consumes the host page :root tokens).
