/* ============================================================
   Wireframe shared styles · sketch-mockup aesthetic
   ============================================================
   All wireframe pages link this file. The look-and-feel matches
   the preferred reference layout (see estimate-review-chat-original.html):
     - Outer thick black frame with simple title bar (no browser chrome)
     - Inner panels nested with their own borders
     - Three-column panel headers (title | italic label | actions)
     - Warmer ecru palette for table/header backgrounds
     - Floating side panels (Financial Metrics & Grading Table style)
     - Chat panels with dark-tan header + window controls
     - Clean rectangular buttons
   Production styling will live in the React app's design system later.
