This module (highlighted): the planner, the Gemini model it asks (amber, a model) and the session history it reads; blue is our own code.

Module 12 (high-level design) drew StyleMe as a graph of three nodes. This module opens the first node, the planner, the part that gives the course its name: before StyleMe searches anything, it decides what the shopper wants. The rest of Part 3 depends on this decision being made well, and safely when the model gets it wrong.
