FLUX Prompt Builder

Local single-file prompt generator for FLUX.1-schnell. Fill in meaningful scene details, then compile them into a coherent prompt built around the prompt patterns commonly seen in curated FLUX examples and the official FLUX prompt framework.
Input
FLUX generally responds better to positive, descriptive prompting. Describe what should be present and how it should look rather than writing long negative-prompt lists.

Structure used: subject → action/state → setting → style → lighting → palette → mood → composition/camera → critical details → exact text.
Why this works
This builder forces the prompt into a clear semantic order so the model gets the main subject first, then scene logic, then visual treatment. That is closer to how strong FLUX prompts are typically written than random tag piles.
