Additional context

We enabled biome checking and fixed reported a11y issues with SVGs missing title by adding the title element to the SVGs. We now see title is rendered in OG.

We have this in production over at www.gredice.com/opengraph-image We applied opacity workaround. Version doesn't seem to be an issue, it was present in 15 too.
