+Added theme tokens for responsive colours. Read these in a themable container
+such as `<rh-card>` to style themable content that responds to the color palette
+
+```html
+<rh-surface color-palette="lighter">
+  <rh-card color-palette="darkest">
+    <p>That way, colours respond to their parents' <code>color-palette</code>
+       Without requiring <a href="#">custom CSS</a></p>
+  </rh-card>
+  <p>Use <a href="#">theme tokens</a> for best results.
+</rh-surface>
+```
+
+```css
+rh-surface {
+  & a {
+    color: var(--rh-color-interactive-blue-normal);
+    &:hover,
+    &:focus-within
+    &:active { color: var(--rh-color-interactive-blue-emphasized); }
+    &:visited {
+      color: var(--rh-color-interactive-purple-normal);

+      &:focus-within
+      &:active { color: var(--rh-color-interactive-purple-emphasized); }
