ConTeXt: bold titles except for maths with regular weight

Question

Here is my code :

\setuphead[section][style={\ssb\bf}]

\starttext
\section{Hi, my name is Arnaud and I love maths: \math{e^{i\pi} = -1}}
\stoptext

I would like it to display Hi, my name is Arnaud and I love maths: in bold but the equation in regular weight. Is that possible? By default, both the text and the equation are bold.

I am asking this because I use two fonts (sans & maths) that are not the same weight even though both are set to bold. In this case, I prefer to clearly distinguish normal text and equations.

Thanks in advance!

Answer 1

Unfortunately, I did not find any high-level switch to turn off automatic font weight deduction for maths. You just have to operate it out of \everymathematics.

\removetoks
    \font_helpers_synchronize_math_family % auto bold
\from \everymathematics

\setuphead[section][style={\ssb\bf}]

\starttext

\startsection[title={Hi, my name is Arnaud and I love maths: \math{e^{i\pi} = -1}}]

  % Manual math bold still works
