This looks really nice, I am just wondering how it would look if you made the line width of the svelte logo slightly thicker. I am no designer, but the line could look a bit jagged or dotted on some displays.

Should be fixed, what do you think?

[realguse]

That definitely made it a lot better, thx

Why is there both a banner and banner_large version? Can't we just use the banner version? Then all references to that img will also be kept stable

[Ocean-OS]

The banner_large versions are higher resolution, I'll delete the lower resolution ones and change the new ones to "banner"

[Ocean-OS]

I made a change so that the banner in the README shows up even if the README is displayed on other sites (eg NPM)
This will only work if the PR is merged, as it assumes the banners are available in the main repository (not my fork)

These are nice changes, but I wonder if they're working. When I visit https://github.com/Ocean-OS/svelte/tree/main I get a dead image

The image URLs will work if the PR is merged, as they use the URLs that the images would be at if they were in this repository, (where the images do not currently exist), so sites like NPM will display the images correctly.

Shoot, I accidentally deleted the changes...

That’s the worst, I do it all the time unfortunately, thats why you backup your computer
