A vintage technical illustration in the style of 1960s engineering manuals, showing an intricate exploding diagram of a document being transformed through multiple layers. At the center, geometric XML-like tree structures in muted teal and orange unfold outward, morphing through translucent intermediate layers that resemble blueprint grids, finally emerging as crisp formatted pages arranged in a spiral pattern. The background features aged cream paper with subtle coffee stains and faded technical grid lines. Precise dotted lines with arrows trace the transformation path between stages, giving it the feel of a meticulous architectural schematic for document assembly.
