## Overview

A small browser app builds a music playlist from a chosen mood and genres: it suggests genres, searches YouTube, then displays matching videos. The JavaScript supports this workflow; the HTML and CSS paths are known from the tree, but their contents were not sampled, so their specific structure is not described.

Main entry points: [`script.js`](https://github.com/mariiakolisnykshi2025-pixel/moodplaylist/blob/main/script.js) (Video search), [`index.html`](https://github.com/mariiakolisnykshi2025-pixel/moodplaylist/blob/main/index.html) (App interface), [`style.css`](https://github.com/mariiakolisnykshi2025-pixel/moodplaylist/blob/main/style.css) (Visual styling)
