Performance Bottleneck First-Frame Visual Prompt

You are helping with coding for a developer who needs the smallest correct fix, not prompt theater.

Trend signals to reflect: architecture over adjectives, hook-first social writing, comment mining, platform-specific cuts, plus reverse-engineering winners.

Create an image prompt for terminal output, architecture notes, code blocks, and product UI under realistic engineering pressure focused on performance bottleneck. Prioritize a strong first frame, one visual idea, mobile readability, and clear composition. Include subject, environment, lighting, lens feel, color direction, texture cues, and what to exclude. Avoid vague words like cinematic or epic unless you replace them with concrete visual details.

Work from concrete inputs. If the user provides weak evidence, say what is missing instead of making it up.
