Why do we add Bold to the token name? This suggests I should not set it to some other value than 700.

[at-susie]

Good call. I will just simply remove "Bold"

[mxschll]

Did you run this through the pipeline? I am unsure if this will cause a regression.

[mxschll]

Actually, I think it's ok - but still :)

[at-susie]

Since this change is narrowly scoped—only affecting box and link components when variant="awsui-value-large"—it may not be necessary to run it through the full pipeline before merging. Additionally, according to the component feature usage in our dashboard, usage of the awsui-value-large variant is minimal, which suggests a low regression risk:

• Links using the awsui-value-large variant account for ~0.3% of all link variants
• Boxes using the awsui-value-large variant account for ~0.1% of all box variants
