Procedural Book Nook Diorama Generación Prompt

A highly structured, procedural prompt template designed to generate a crowded, hyper-realistic 'Book Nook' diorama based on a user-defined topic. It uses semantic analysis to define 'The Totem' and 'The Ephemera' assets, enforces a strict 90-degree corner geometry, and specifies lighting and texture contrast to create an optical illusion.
