older browsers don't support light-dark, so links appear the same color as normal text. this makes linked text underlined on unsupported browsers to make it more visible

suggested by @olifloof - thanks!!!

still a work-in-progress, current changes include
- major redesign and cleanup
- themes now work as userstyles so you can add them to your manager to override any dev.css site's theme
- improved readme

to do:
- finish dev.css-docs and move demo to that site
- update dev.css preview images

uses https://github.com/xz/new.css/issues/86

change made for consistency across the page

uses the snippet from vscode (along with geist and inter in front)

oops

kinda hacky? sorry, maybe there's a better way to do it. should still work fine tho

uses it across the document, so scrollbars are also themed

also remove the intergrav/fonts imports section, since you should visit intergrav/fonts readme for that

oops
