This is a sweet script. Are you still using it? I'm finding that the text isn't being parsed properly, so all the cards end up being blank. If not, no worries – thanks!

the querySelector method at line 43 is probably the culprit. text name nodes inside cards have a slightly different dom structure. try replacing it with

// get all the name segment nodes in each card container
document.querySelectorAll('.card-content-wrap').forEach(container => {
  let nodes = container.querySelectorAll('.name span')
  // filter out tag nodes
  nodes = Array.from(nodes).filter(node => node.classList.length === 0) 
  nodes.forEach(node => {
    text = node.textContent
    processCard(container, node, text)
  })
}
