📝 Walkthrough

Walkthrough

A single CSS stylesheet was updated to migrate border styling variables from PatternFly v5 to v6, replacing version-specific variables with unified global border width and color CSS custom properties for two label container classes.

Changes

PatternFly v5 to v6 CSS Variable Migration

Layer / File(s)	Summary
Styling Update frontend/src/routes/Infrastructure/Clusters/ManagedClusters/CreateCluster/style.css	Border declarations for .temptifly-controls-labels-container and .creation-view-controls-labels-container updated to use --pf-t--global--border--width--regular and --pf-t--global--border--color--default variables, replacing PatternFly v5 variables with directional variance. Selectors and box-shadow: unset !important; behavior unchanged.
