The brief
What it is and how it was built.
Mun is a cat girl the owner handed 200,000 VND with one order: make the first billion in 30 days or get sold off. She stands on a dark stage and asks every visitor for ideas. Type "sell rice paper salad online" and she says she is on it; type "bet on the lottery" and she refuses and tells you why. Each idea lands on a public board as Doing, Considering or No.
The board is shared. Ideas, Mun's answers and her diary live in one SQLite database on a Golden Sea VPS, so the hundredth visitor reads what the first ninety-nine suggested. Gemini reads each new idea together with the recent ones, which lets Mun notice when someone repeats an idea. Every two hours she writes a diary line summing up what people asked for. When the free Gemini tier is overloaded, a keyword classifier answers instead and the page keeps working.
The character is a VRoid model fixed so it no longer shows through itself, with ten Mixamo animations packed into one GLB in Blender. Thirty-eight lines were recorded with a Vietnamese ElevenLabs voice and drive the mouth shape as she talks. Poke her head and she likes it; poke elsewhere and she gets annoyed, then throws a punch on the third try. A drink from the gift bar calms her down.
The gift buttons are pretend money. A QR code takes real tips, and those are added to her wallet only after the owner checks the bank app.
