/**
 * File:          public/css/voice_notes.css
 * Version:       0.1.0
 * Last Modified: 2026-07-22
 * Changes:       New — styles for the Voice Notes feature (mic capture + library +
 *                karaoke) that feeds cleaned transcripts into the Prompt Builder.
 *                Everything is namespaced .vn- / #vn-modal so it never collides
 *                with app.js styles. Colors come from the app's CSS variables
 *                (dark-mode aware) with hex fallbacks.
