description	Create a new Read-to-Earn lesson (readings, fun facts, questions, fill-in-blanks, environment prompts) for a building, following the established LessonContent pattern. Use when Marina says "write a lesson for X", "add a building lesson", "/add-building-lesson", or a building has no lesson content yet.

Help create a new building lesson. Ask the user which building needs a lesson, then:

1. Read RenaissanceArchitectAcademy/Models/LessonContent.swift for the router pattern
2. Read RenaissanceArchitectAcademy/Models/LessonContentRome.swift or LessonContentRenaissance.swift for examples
3. Read RenaissanceArchitectAcademy/Models/BuildingLesson.swift for section types

Create a lesson with ~18-22 sections including:

• Reading sections with educational content about the building's 3 sciences
• Fun facts with engaging historical details
• Questions with 4 multiple-choice answers
• Fill-in-the-blank exercises
• Math visuals where appropriate
• Environment prompts linking to workshop/forest

Follow the Morgan Housel writing style: punchy, story-driven, ~60-80 words per section. Add the lesson to the appropriate content file and update the router in LessonContent.swift.
