Square Frame Icon - Placeholder & Selection Boundary Symbol #3753421 (License: Personal Use)

This vector-style icon features a bold black outer square with softly rounded corners and an inner dashed-line rectangle, creating a layered border effect. The design suggests a boundary or container, often used in graphic editors, wireframes, or CMS interfaces to indicate where content will be placed or selected. Its neutral, monochrome aesthetic ensures high versatility across light and dark themes.

Typically used in web and app design as a placeholder for images, videos, or editable regions; also appears in drag-and-drop interfaces, cropping tools, and UI kits to signal selection or focus areas. Matches user intent for visual scaffolding, template design, or indicating interactive zones.
