Math and isotopes not properly rendered on HTML export

[gerchowl]

Description

Math notation and isotope symbols are not being properly rendered when exporting to HTML format.

Current Behavior

When exporting documentation to HTML, mathematical expressions and isotope notations (from the lib/notations.typ system) are not displaying correctly.

Expected Behavior

Math and isotope notations should render properly in HTML output, similar to how they appear in PDF output.

Context

• The notation system was recently added in the lib/notations.typ file
• HTML export was enabled using html.frame show rule
• This affects the readability of technical documentation in HTML format

Related Files

• lib/notations.typ - DRY isotope and tracer notation system
• Documents using math and isotope notations

Steps to Reproduce

1. Build documentation with math/isotope notations to HTML format
2. View the HTML output
3. Observe that math and isotopes are not rendering correctly
