fixes certain issues with the header appearing below things sometimes

set to 1000 to make sure it appears above everything, unless other elements have a higher value which is unlikely

you can use multiple articles in the aside element to allow for multiple containers in a sidebar.

also, the second aside element will now appear on the right of the page

if for whatever reason you dont have a header on your page, it won't look cramped anymore

- simplify font stack significantly
- clean boilerplate theme
- replace boilerplate with boilerplate-auto for simplicity (you can still make static color themes)

cleanup of the font stack, now using https://systemfontstack.com

windows 11 font, havent tested yet cuz im on mac but it should work :p

suggested by @olifloof - thanks!!!

still a work-in-progress, current changes include

- 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
