🗒 Checklist 🗒

• I have read and followed Catppuccin's submission guidelines.
• I have made a new directory underneath /styles/<name-of-website> containing the contents of the /template directory.
  • I have ensured that the new directory is in lower-kebab-case.
  • I have followed the template and kept the preprocessor as LESS.
• I have made sure to update the userstyles.yml file with information about the new userstyle.
• I have included the following files:
  • catppuccin.user.less - all the CSS for the userstyle, based on the template.
  • preview.webp - composite image of all four individual flavor screenshots (taken with the default accent color of mauve) stitched together, generated via Catwalk.

When theming the authentication dialog, it seems that's an iframe on the page. Should that be separated into its own theme? Or should all apple websites be under the same theme? (rename this to just "apple"?)
I'd like to theme the Apple Developer site in the future and it looks like it uses the same auth iframe.

Also curious as to if this is ok or not:
before:

after:

The colors change based on selected theme color.

And as a side-note i see this PR for apple developer docs: #1044
Doesn't theme the account page however.
