Copilot: I'd be happy to write a story for you! Here's a short one:

**The Last Library**

Maya found the building by accident, half-buried beneath centuries of sand. The sign was still legible: *Public Library*.

Inside, dust motes danced in shafts of sunlight piercing the cracked ceiling. Rows of shelves stood like ancient sentinels, their contents miraculously preserved by the desert's dry embrace.

She ran her fingers along leather spines, pulling one free. The pages crackled as she opened it—a cookbook from 2024. Another book showed children playing in green parks. Another described something called "rain."

Maya had only seen water rationed in plastic pouches. She had never seen a tree that wasn't synthetic.

She spent hours there, discovering a world where people worried about things like traffic and what to cook for dinner. Small problems. Beautiful problems.

When she finally emerged, the twin suns were setting. Under her arm: three books. In her chest: something dangerous.

Hope.

Would you like me to write a different type of story, or is there something specific you'd like me to help you with in this project directory?
Session is idle.
