@dan I have noticed something strange going on with text in the latest build.
If I have some text set to be SEMI-BOLD, there are times at different breakpoints where it appears to switch to BOLD. This only shows up in the browser, not in the editor. See below.
I think the issue you’re seeing is likely due to the fact that the “semi bold” font weight isn’t supported by the Righteous font you’re using for the headings.
The “Enhance the flow…” heading is using the Righteous font family with a font weight of 600 (semi bold). However, Righteous only includes a single weight—400—so applying 600 won’t have any visual effect (or the browser might do strange things, like in this case).
To fix this, you have two options:
Set the heading font weight to Normal (400)
Or switch to a font that supports multiple weights
