Unable to capture live TUI screenshots without an active Klaatu account for
auth. Happy to add screenshots if a reviewer can confirm the themes render
correctly, or if there is an offline/mock mode I can use. @aakashrajput

@siddhanttiwari19 you can create a free KlaatAi account on https://klaatai.com and once you run klaatcode it will auto login you and you can take the screenshots and even use klaatcode.

free accounts gives you 75 requests per day.

Happy Coding.

Hey, quick update , I made a KlaatAI account and tried running klaatcode to auto-login, but I'm hitting a snag: the browser keeps showing "can't reach this page" on the localhost callback URL after I try to sign in. Tried a few different things on my end (different ports, checked firewall, etc.) but no luck so far, might be a Windows-specific thing.

Still trying to sort it out, but in the meantime the values I added are pulled straight from the official Catppuccin palette (catppuccin.com or palette), following the exact same pattern as the existing CATPPUCCIN_PALETTE already in the file. If it'd be quicker for you to just glance over the hex codes than wait on me fighting local auth, happy to have you take a look that way too. Will keep trying on my end regardless. @aakashrajput

@siddhanttiwari19 thanks for the update , we are looking into it on priority, will let you know once it starts working.

Hi @aakashrajput, thanks for the update! the merge conflicts have been resolved and all checks are passing. Since the localhost login issue is still being investigated, I can't attach the screenshots yet.
If everything else looks good, could you please merge the PR? Thanks!

[aakashrajput]

Hi @siddhanttiwari19 thanks for waiting, can you please take a back merge into your repo and try to run it it will be working now. Thanks

[siddhanttiwari19]

Hi @aakashrajput, I merged the latest main and verified the login flow is working again. I tested the three new Catppuccin themes and attached screenshots int the PR description. The themes are selectable and apply successfully. The visual differences between Latte, Frappé, and Macchiato are fairly subtle on the current UI, but the palette registration and theme switching are functioning correctly.
