/* ==========================================================================
   artifact-viewer.css — Orcheum-owned PDF preview surface
   --------------------------------------------------------------------------
   Conversation file cards keep their existing shape. Opening a PDF reveals a
   workspace-contained viewer: Orcheum chrome around an Adobe SIZED_CONTAINER
   document area. Adobe never owns the application shell.
   ========================================================================== */

/* The conversation's generated-file row is NOT here any more. It is the kit
   component 166:3466 (components/chat/generated-file.css); this file owns the
   PDF/spreadsheet viewer alone. The `.msg-file--document` rules that stood
   here — a 16px mark, a single crammed label, and two 10px chips on a tint —
   are deleted, not overridden. */
