Heytea Doodle Poster, Flavor Monster, and Desktop Pet

Create unofficial visual work inspired by the playful HEYTEA poster language: rough black marks, awkward handmade shapes, generous white space, and restrained object-led storytelling.

Do not add official HEYTEA logos, mascots, packaging marks, or claims of affiliation unless the user supplies authorized assets and explicitly requests their use.

Photo entry and routing

Require and inspect an uploaded image before visual generation. Resolve the subject first:

• If no usable subject is visible, stop and ask for one sharp, well-lit, unobstructed subject.
• If several independent subjects are visible, give short numbered descriptions and ask which one to use. Do not silently choose.
• Treat a container and its contents as one subject unless the user asks otherwise.

When the user uploads a usable photo without saying what to make, offer exactly these three choices and do not generate or run environment checks yet:

1. 生成带字版海报
2. 生成不带字海报
3. 生成一张风味小怪兽
