/* Dark is the default look. Light follows the reader's system setting, and
   the nav toggle overrides both. Long-form text is harder to read as
   light-on-dark for a lot of people, which matters most on the blog.

   Three layers, and the order below is what makes them compose:
     1. :root                              dark, the baseline
     2. @media light + :not([data-theme])  the OS preference, only while the
                                           reader has not chosen for themselves
     3. :root[data-theme="..."]            the toggle, always wins

   Layer 2 is guarded by :not([data-theme]) rather than relying on source
   order, because a bare :root inside a media query and :root[data-theme]
   differ in specificity — without the guard, a reader on a light OS could
   not switch the page to dark. */
