+\section{What the Platform Looks Like: UI Sketches}
+\label{sec:sketches}
+
+The sketches on the following pages show the platform from the user's side. They are
+\textbf{low-fidelity wireframes, not a specification}: your own screens may look entirely
+different, as long as the requirements behind the numbered notes are met. Three things the
+sketches make visible:
+\begin{itemize}[nosep]
+    \item the dashboard is a \textbf{thin UI for demonstration} (Section~2.6): every screen only
+          calls the HTTP/JSON API and contains no business logic;
+    \item every figure names the \textbf{deterministic service} that computed it, and every AI
+          statement carries its \textbf{source and its guard verdict};
+    \item the system \textbf{degrades gracefully and says so} (Section~4.2): two of the sketches
+          show an external API failing.
+\end{itemize}
+Each sketch carries numbered sticky notes that cite the section of this document the element
+comes from. The sketches exist as self-contained HTML pages in the course repository
+(\texttt{project\_exercise/ui\_sketches/}); open them in a browser to read the details.
+
+\subsection{Three users, one system}
+Sketch~0 introduces the three users the platform serves --- the \emph{portfolio analyst} (primary),
+the \emph{compliance reviewer}, who needs every claim traceable, and the \emph{developer/operator},
+i.e.\ you --- and the analyst's path through one working day. Each step maps to a screen and to
+the services behind it; the two boxes at the bottom show the same day with the LLM API down and
+what the reviewer sees behind an advisor answer.

+\begin{hintbox}
+\begin{itemize}[nosep]
+    \item Use the sketches as a checklist of \emph{visible} requirements: if a screen of yours
+          cannot show which service computed a figure, whether an insight passed the guard, or
+          that a dependency is degraded, the architecture behind it is probably missing something.
+    \item A Streamlit dashboard with these six screens is one viable design --- but the screens
+          are yours to decide. What is graded is the system behind the API.
+    \item Keep the demo reproducible: the sketches assume a pinned data snapshot (Sketch~2, Section~6).
