At Rails World 2025, I introduced ReActionView, an initiative to explore what's possible in the Rails view layer for 2025 and beyond.
As part of this, I announced Herb::Engine, an ActionView-compatible ERB engine built on top of the HTML-aware Herb Parser.

Shoutout to @marcoroth.dev for Herb. Just fixed a bunch of small typos in our HTML that it found.
Browsers are pretty good at fixing these issues automatically, but I'd sure rather be sending correct HTML instead.
