Create a modern, eye-catching, and AI-inspired Instagram post and reel cover design for the page "PROMPT BY AI". The main color theme is deep blue (#1F2C56), with light purple (#C2B6F4) as secondary and neon digital green (#00FFAB) as accent. For reels, include a transparent background version that features the futuristic AI-brain logo and a dynamic tech-inspired frame. For posts, include dedicated space for a headline and a short hook (text area), all positioned to follow the 2025 Instagram algorithm best practices (top-left title, middle eye-catcher, clean CTA space). The design should feel intelligent, minimal, futuristic, and brand-cohesive.
