🎉 Theme for Gleam 🎉

💬 Additional Comments 💬

I don't think we can call this just gleam since there is already a catppuccin/gleam and I don't want to intentionally create more port "duplicates".

🗒 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.
