Here's a good step-by-step tutorial, and here is where I finally got search to work.
Apparently helpd only observes a few directories to update its index, and Xcode build output directories aren't included. Copy the binary to /Applications.

Use NSString's stringByAbbreviatingWithTildeInPath

Find the symbol you want in the SF Symbols app and select it, then Edit > Copy Image As... to copy the SVG into the pasteboard. Paste into a text editor and save as a .svg file. It can then be used in HTML as
<img src="icon.svg" />
Use https://codepen.io/sosuke/pen/Pjoqqp to generate the filter and set it in CSS.
