immediate todo

fix the site-toc generation being out of date (each [sub]directory of xref needs a central xrefs db which triggers a rebuild of all pages at that level if a new page is added)
make deftech/tech actually work
make some CSS
site nav should use titles instead of slugs
user pages
search form (+ actual fulltext indexing lol)
page tags should link to the tag index

wishlist

prefers-color-scheme
robots.txt, sitemap.xml
firefox alternative stylesheets too maybe (send more js for chrome to do the thing too)
make /unsupported-browser page for brave
rss/atom
indieweb: microformats2, webmentions, websub, rel=me
support tor and opennic
activitypub
gopher and gemini variants
support for lynx (basic html) and raw curl (ansi codes)
meta generator
meta theme-color, manifest, etc. weird mobile stuff
stylesheet integrity attribute
rel noopener noreferrer
license and rel=license
more semantic rel: rel=icon, rel=home, rel=prev/next, rel=author, rel=canonical etc
pronouns? make up a rel=pronouns or something because uwu
nginx caching headers
look at cybre/masto for more weird vendor meta tags
