<final_analysis>
The page follows the about page brief with a dossier-style long read: a sticky stage index on the left, warm paper content layers alternating with deep ink panels, a four-step workflow with a contour tick metaphor, numbered team labels, and a phase list. Placements for images are in the workflow, team, and Guizhou sections. Copy stays client-facing and avoids governance meta-language.
