Do not namespace margin utilities for scale values 0, 1, and 2

[Copilot]

What are you trying to accomplish?

Remove the pr- namespaced versions of margin utility classes for scale values 0, 1, and 2. Only generate .pr-m*-{scale} classes for scale ≥ 3.

What approach did you choose and why?

Added @if ($scale >= 3) conditionals before outputting .pr-* prefixed selectors in margin.scss. This affects all margin utilities:

• .pr-m-*, .pr-mt-*, .pr-mb-*, .pr-mr-*, .pr-ml-*, .pr-mx-*, .pr-my-*
• Negative variants: .pr-mt-n*, .pr-mb-n*, .pr-mr-n*, .pr-ml-n*

Used a combined condition @if ($scale >= 3 and $scale < length($spacer-map-rem)) for negative margin right/left to stay within stylelint's max-nesting-depth rule.

What should reviewers focus on?

• Verify the conditional logic correctly excludes scale 0, 1, 2 while preserving scale 3+
• Non-prefixed classes (.m-0, .mt-1, etc.) are unchanged and generated for all scales

Can these changes ship as is?

• Yes, this PR does not depend on additional changes. 🚢

Original prompt

On margin.scss, Do not namespace for scale values 0, 1 and 2
