Is your feature request related to a problem? Please describe.

Currently, this extension results in 50+ kB of assets across 7+ network requests to be added to each page for a project's documentation.

Describe the solution you'd like

Significantly lowered payload size (drop the dependency on semantic-ui?) and consolidate CSS/JS files to reduce the number of network requests needed.

Describe alternatives you've considered

A clear and concise description of any alternative solutions or features you've considered.

Additional context

This would also make it easier for "downstream" themes to customize how the tabs look, if the CSS for this project is self-contained in a single file. :)
