Clean, self-contained SVGs of the key schematics — drop them into your own notes or slides. Vector, so they scale crisply; recolor by editing the stroke values.
To use one: open the .svg and right-click → save, or drag it straight into Google Slides / PowerPoint / Keynote / Figma / Excalidraw. SVGs are editable vector — fonts fall back to your system if Space Grotesk / IBM Plex aren't installed.
