For about a month, every social preview card on a site I build was silently cut off mid-word. Not truncated with an ellipsis — cut inside a word. PDF & image tools, con. The con is converters, sliced in half.
Nobody reported it. Preview cards are the one thing you never see on your own site — they only show up when someone else shares your link on Slack, Discord, or X. So it just sat there, on every page, in every language.
Here's the line that did it:
// OG card subtitle
<text ...>${esc(String(sub).slice(0, 60))}</text>
