Extend an existing icon set

The existing files are the specification. Recover their decisions, then make the selected icons disappear into the set. A new or redrawn icon fails when a stranger can identify it as the addition, even if it looks good alone.

Copy quirks that define the set. Correct defects that break rendering. A heavy stroke or odd arrowhead may be a quirk. A clipped stroke, merged shape, or fixed color that breaks theming is a defect. When one icon cannot settle the distinction, match the set and report the issue.
