What is the issue and how can we reproduce it?

1. Open the sample OpenUi5 Documentation

After updating to version 1.136, we noticed that some text appears excessively bold when using the standard theme.
Upon inspecting the applied styles, we found that the --sapFontHeaderFamily variable resolves to the following font stack:

"72-Bold", "72-Boldfull", "72", "72full", Arial, Helvetica, sans-serif

It appears that the inclusion of "72-Bold" and "72-Boldfull" causes significantly heavier font rendering compared to previous versions. This is particularly visible in headers and negatively affects the visual appearance of the UI.

We have tested the issue in version 1.138, where the problem no longer occurs — the font rendering looks balanced and consistent again.

However, since 1.136 is currently the latest LTS version, we would like to ask if it would be possible to receive a hotfix for this version, or if any backporting is planned to address the issue.

Thank you for your support. I'm available for any further clarification if needed.
