Common use cases
- Frame a photo for a gallery or portfolio display.
- Add a coloured mat around an image for print layouts.
- Create a polaroid-style border for social media posts.
- Give screenshots a visible edge for documentation.
Limitations
- The border is uniform on all four sides; per-side widths are not supported in this build.
- Border styles are limited to solid colours — no gradients, patterns or rounded corners.
- The border increases the canvas dimensions, so the output image is larger than the original.
