P2: The old flexbox syntax (`-webkit-box-align`, `-ms-flex-align`) uses different alignment values than the standard. Passing `flex-start`/`flex-end` directly won't work — old browsers expect `start`/`end`. If these prefixes are needed, the mixin should map values (e.g., strip the `flex-` prefix for legacy properties). If old browser support isn't required, consider dropping the legacy prefixes entirely and using Autoprefixer instead.</violation>

P2: `-ms-align-items` is not a valid CSS property and will be silently ignored. The correct IE10 prefix (`-ms-flex-align`) is already included on the line above. Remove this invalid property.</violation>

P2: `-webkit-box-ordinal-group` is 1-based while `order` is 0-based. Passing the same value directly produces off-by-one ordering in old WebKit. The value should be `$val + 1` for the legacy property, or drop the legacy prefix if old browser support is unnecessary.</violation>

P2: -webkit-box-ordinal-group is 1-based while order is 0-based. Passing the same value directly produces off-by-one ordering in old WebKit. The value should be $val + 1 for the legacy property, or drop the legacy prefix if old browser support is unnecessary.

P2: -ms-align-items is not a valid CSS property and will be silently ignored. The correct IE10 prefix (-ms-flex-align) is already included on the line above. Remove this invalid property.

P2: Adding display: flex to .small-action makes the float declarations on its children (.topic-avatar, .avatar, button) dead code—per the CSS spec, float has no effect on flex items. These should be removed to avoid confusion and ensure the layout relies solely on flexbox properties (e.g., use margin-left: auto on button instead of float: right to push it to the right). The clear: both on .small-action itself is also now unnecessary.
