+
+- **Canvi de mode clar/fosc**. S'activa establint `theme_switcher = true`. (~900 bytes)
+- **Còpia de blocs de codi amb un sol clic**. S'activa establint `copy_button = true`. (~700 bytes)

+
+This theme has no mandatory JavaScript. Optionally, it can load a minimal amount to add some features that are impossible to achieve with HTML and CSS:
