## Before you start
Ask what the user's product and brand are, then apply these principles to that product rather than reproducing the reference.

Create a left product-navigation rail for a desktop marketing/product overview page. Make it approximately 230px wide, separated from the main canvas by a very light vertical rule around `#eeeae6`, with a compact wordmark area at the top, vertically stacked links, and clear active-state treatment. Use a warm off-white background around `#fcfbf9`; active items get a soft peach fill around `#ffe4dc` and dark text; secondary and nested links use smaller muted gray text and indentation. Include section groupings, small “new” badges where useful, and a bottom dark-mode toggle row. Use a clean sans-serif, 12–14px navigation text, 8–10px vertical gaps, and avoid visual heaviness. On mobile, collapse this into a top drawer or horizontal menu.

Never: use logos, product names, copy, illustrations, or imagery from the reference.
