Monospace font is missing box-drawing characters, breaks ASCII charts

Some pages like https://lmstudio.ai/docs/developer/openai-compat/tools#high-level-flow include ASCII charts.

All box-drawing characters are absent in Geist Mono (the monospace font used by the theme), causing the browser to instead use the fallback fonts for those characters:

The Google Fonts type tester demonstrates this nicely when pasting the chart into it:

Judging by the search results for "───" there are only two other ASCII charts, both of which are still very readable:

• https://lmstudio.ai/docs/typescript/agent/act#automatic-tool-calling

Rather than fixing the font it might be easier to replace the tool use chart with e.g. a Mermaid SVG?
