https://docs.emdashcms.com/ ("Create your first EmDash site"); the
--yes defaults are cloudflare + blog. Replaces the old madmode/
starter (never committed).

+  theme.css -- your theme overrides. This is the file to edit to
+  retheme the site.
+
+  Every design token lives in src/styles/tokens.css (colors, type
+  scale, spacing, layout, shadows) with its default value. Override any
+  of them here: declarations in this file are unlayered, so they always
+  beat the @layer base defaults in tokens.css.
+
+  Colors are defined with light-dark(). Overriding with a plain color
+  changes light and dark mode at once; use light-dark(<light>, <dark>)
+  to set different values per mode.
+
+  Webfonts are loaded in astro.config.mjs (--font-body, --font-mono).
+  Swap the loaded font there; use overrides here for system fonts or a
+  separate heading face.
+
+  Example:
+
+  :root {
+    --color-brand: light-dark(#0f766e, #2dd4bf);
+    --font-heading: "Iowan Old Style", Georgia, serif;
+    --radius: 8px;
+  }
