Temporal is estimated to land in Chrome 144 which becomes stable on 7th January 2026. This could change.

Temporal is already available in Firefox and is in development for Safari.

That caught me out too. There's too much dry meat.

That's illegal.

Also, the gravy is meant to fill and overflow the yorkshire. Pre-filling with peas is acceptable but you've overstepped by putting carrots in there too.

Please tell me that is cauliflower cheese and not macaroni cheese hiding top left.

For basic glossary access, I suspect they fetch a cached human-reviewed definitions. It's cheaper and eliminates the unpredictability risk. Some children will miss out on that due to the paywall.

For the interactive Q&A, I'm curious if it will go beyond pre-canned. Might pay to experiment.
