Create a high-resolution 16:9 canvas (minimum 1920x1080 pixels) designed for a full-screen website background, featuring a vibrant and energetic geometric pattern. Utilize a dynamic interplay of bright colors, including electric blue (#007BFF), vivid orange (#FF5733), and neon green (#39FF14). The pattern should consist of bold lines and stripes that intersect at various angles, creating a sense of movement and excitement. Ensure the geometric shapes vary in size, with larger elements dominating the canvas while smaller shapes fill in the gaps, achieving a balanced yet lively composition. Incorporate a smooth gradient effect that transitions between the bright colors, enhancing the visual appeal and creating depth. Consider using vector graphics software for precision and clarity, and apply a subtle texture overlay in post-production to enrich the overall appearance. The final output should be saved as img_2031.heic for optimal quality.
