/* ============================================================================
   DATA-PIPELINE DIAGRAM — shared component
   ----------------------------------------------------------------------------
   The animated input → Tvyal → output diagram. Structure + skin + animation
   live here ONCE. Markup is generated at runtime by js/consultation-animation.js
   (buildDiagram()); this file is the ONLY stylesheet that styles it.

   Loaded by:
     • consultation-popup.html  (the consultation popup, in modal.js's iframe)
     • event.html               (/event, with the .diagram-deapple host skin)

   Both hosts load design-system.css FIRST, so every colour var used here
   (--card-bg-color --border-color --color-main --color-second --icon-blue
   --text-color --transition-speed --accent --radius-sm) resolves globally, and
   @keyframes fadeIn comes from design-system.css — we do NOT redefine it here
   (redefining it would silently change every .fade-in on the host page).
   @keyframes pulse and logoSuccess are diagram-specific and live here; the JS
   references `pulse` BY NAME, so keep that name.
