   Paddy Prompt Studio — Syllable counter for lyrics
   Layers on /blog/style.css (same dark indigo/cyan palette and type scale).
   Only the editor widget lives here; prose styling is inherited.

   Theming: every colour below comes from a custom property. The palette
   variables (--bg, --card, --indigo, --cyan, ...) are the site-wide ones from
   /blog/style.css; the --sc-* tokens are this tool's own and can be swapped
   in one place.
