🔷 Medium: -ms-align-items is not a valid property (IE10/11 use -ms-flex-align). Keeping it can cause warnings without effect. Removing it tightens compatibility without changing behavior.

align-items:$alignment;
}

@mixin order($val) {
-webkit-box-ordinal-group: $val;

🔷 Medium: Legacy WebKit/Gecko box-ordinal-group uses a 1-based index (default 1), while modern flexbox order is 0-based (default 0). Passing the same $val yields an off-by-one in older engines (e.g., @include order(3) results in legacy ordering as 2). Map legacy values to $val + 1 to keep ordering consistent across browsers.

-moz-box-ordinal-group: $val;
-ms-flex-order: $val;
-webkit-order: $val;
order: $val;
