-       group-by modes (severity, file, rule). currentColor + no
-       fill on the outline lets VS Code tint the icon for active /
-       inactive / hover states in the activity bar. -->

+  <!-- Shield outline + check, monochrome — the activity-bar mirrors
+       the marketplace icon's shield motif. `currentColor` lets VS
+       Code tint the glyph: gray for inactive, white for active,
+       theme-foreground on hover. No brand colours here on purpose;
+       a custom hex would fight the activity-bar tint and look
+       wrong on every theme. -->
