/* ==========================================================================
   editorial-response.css — Adaptive Editorial Response (Figma 498:973 / 499:1227)
   --------------------------------------------------------------------------
   ONE reusable response surface driven by structured data. The Figma Hans Zimmer
   frame is sample content only — this file owns the visual grammar (title,
   gallery, intro, sections, dividers) while content varies per response.

   Extends the existing `.msg-answer` token layer in orchestration.css; does not
   fork it. Namespaced `.oc-ed` for editorial-specific layout only.
   Source of truth: Figma "New Chat — response ready" (498:973).
