Develop a Facebook graphic with dimensions 1200x630px for an AI art free class welcome post. Choose a clean, light background (e.g., soft white or light gray) with subtle tech patterns (e.g., circuit lines or abstract shapes) in a slightly darker shade to add texture. Feature the text "Welcome" prominently in bold, large font (e.g., Montserrat) at the center in a dark color (e.g., navy or charcoal) for high contrast. Below it, write "Class will start @9 PM" in a smaller, stylish font (e.g., Lato) in a complementary color, ensuring it is aligned directly beneath "Welcome." Surround the text with vector images of a laptop, mouse, and mobile device, ensuring they are stylized and harmonize with the overall color palette. Position these elements to frame the text, creating a balanced and inviting design. Consider adding subtle drop shadows to the text for enhanced readability and a slight glow effect to create a welcoming ambiance. Ensure the overall layout is clean and well-structured, leaving ample breathing space around key elements for readability.
