The SVG of every style: https://gentleface.com/icons/flag-swallowtail.json (`svg`).

## Code (line-round)

The snippets are decorative (aria-hidden). For an icon that carries meaning on its own, such as an icon-only button, label the button, or give the SVG role="img" and an aria-label. For another style, take its SVG from the JSON and swap the path `d`.
