/* alexgruenberg.com - the one stylesheet.

   Every page links only this file. Each page carries its name as a class on
   <html> (home, darkroom, notfound), and its rules sit inside that page's
   block - :where(.home) { ... } - written with CSS nesting. :where() adds no
   specificity, so a page's rules cascade exactly as plain selectors would.
   Inside a block, `&` means the page's own root element.

   build.py flattens the nesting when it builds dist/, so every browser -
   including older ones without nesting support - receives plain CSS.
   Order: fonts and animations, each page's rules, then the type and film
   layer that applies everywhere, then the rules that replaced inline styles.
