Renders macOS Big Sur style notification banners with frosted glass backgrounds, app icons, and title/body text. Built for video overlays or product launch teasers. The template nails the authentic look: 14px rounded corners, backdrop blur with saturation boost, proper shadows, and SF Pro typography. Icons are CSS-based gradients with emoji, no external images. Ships with light and dark modes, optional slide-in animation, and can either output a standalone 480×120 banner or overlay onto 1920×1080 video with transparency. The whole thing is a single HTML file with webkit prefixes for Safari. If you need a notification screenshot that doesn't look fake, this is it.
