Thanks for the feedback! Will work on some updates for the hero backgrounds. On your point about local code vs. API: - We handle all the authentication, rate limiting, and API differences between providers, which becomes complex when workin

Didn't catch the pricing bug, will update right now. A few others have also mentioned about the Grok & Groq confusion. Will think through some ideas here and update. Appreciate the feedback!

You're right, it wasn't too difficult to guess the location without the stars. The base did happen to be right in-between the 34 and 35 degree lines (34.6 lat), and you can estimate pretty well with only one line
