/* ============================================================================
   Pro UI — IMAGING surface (inline image_generate message-embed chrome).
   LOCKED Pro canon. Loaded via <link href="/static/pro-imaging.css">.
   Flag-gated: only emitted when window.proFlag('imaging') is true.

   SCOPING CONTRACT: every selector is scoped under the unique root `.pro-img`
   (a class the message renderer adds to the assistant image block). It must
   NOT collide with chat-slim.css generic classes (.card/.head/.meta/.body/etc).
   All colors/fonts come from pro-tokens.css vars — nothing hardcoded.

   Chrome only: the FRAME, provenance CHIP, META line, echoed PROMPT, and the
   ACTION row. The generated image itself is content (never styled here).
