The obsidian-tikzjax bundle emits SVG referencing Computer Modern font families like cmbx7 but ships the @font-face declarations in a separate styles.css. Without it the browser substitutes a default font whose glyph widths don't match TeX's, leaving visible gaps between each kerned text run. Lazy-load the stylesheet alongside the engine on first TikZ render so cache hits and misses both see correct fonts.
