PixTaffy v0.30.0

Added

• A real three-credit balance for unregistered visitors, enforced against both the anonymous Firebase identity and the browser installation.
• A protected guest-balance endpoint so the studio can show remaining credits without delaying the public welcome page.
• Guest-ledger tests and a clean-browser smoke path for blocked guest-session dependencies.

Changed

• GPT Image 2 is now the default for new visitors and accounts. Its two-credit guest run leaves one credit for a Standard image.
• Email-verified starter credits increased from five to ten.
• Guest visitors can choose PixTaffy-funded models and see generation cost and remaining balance.
• The primary welcome action now says “Create your first image.”

Fixed

• Anonymous-session and generation waits now end in visible errors instead of endless loading states.
• Local development can use a registered App Check debug token without including it in production builds.
• Guest request keys rotate after successful delivery so an older cached image cannot replace a new request.
