+  theme.css -- override any :root variable here to retheme the site.
+
+  This is the only file you need to edit to customize the site's visual
+  appearance. All defaults are listed below as comments. Uncomment and
+  change any value to override it.
+
+  Base.astro puts its defaults inside @layer base, so declarations here
+  (which are unlayered) always take priority -- no specificity tricks needed.
+
+  Note: this template defines explicit dark mode colors in Base.astro.
+  Overriding light-mode --color-* variables here won't affect dark mode.
+  To customize dark mode, also override --color-* variables inside a
+  @media (prefers-color-scheme: dark) block and/or in the :root.dark rule.
