Fix SwiftUI Layout Issues with Scalable Padding

A walkthrough of using SwiftUI's @ScaledMetric property wrapper to create dynamic, accessibility-aware padding values. By setting a scaled metric relative to a specific font style (e.g., body), padding values automatically grow or shrink when the user changes their Dynamic Type size, rather than remaining fixed pixel values. The example demonstrates defining a small padding variable of 8 points relative to the body font style.
