   GeekTragedie's Wonderland - shared site styles
   Every page links this file. Page-specific styles stay in
   the page itself. To change a page's background photo,
   override `background-image` on body in the page's <style>
   (keep the overlay gradient first), e.g.:
     body { background-image:
         linear-gradient(var(--overlay-color), var(--overlay-color)),
         url('./bird-eggs.jpg'); }
   To change a page's accent, set `body { --accent: ...; }`.
