What problem does it solve? It turns structured bilingual or multilingual educational content into a self-contained interactive HTML study page where learners can toggle pronunciation and translation tracks on or off, then publishes it to GitHub for mobile access. ## Core Features & Use Cases - Three-track content model: Every text block carries a source-language track, a phonetic/romaji track, and a translation track, each mapped to dedicated CSS classes. - Visibility toggle bar: A sticky header with buttons for Japanese-only mode, romaji toggle, and English toggle, plus live status dots driven by a small JavaScript state object. - GitHub deployment workflow: Creates a public repo, pushes the HTML file, and produces an htmlpreview.github.io URL for phone viewing. - Use Case: A language learner asks for a Japanese business keigo practice page; the skill generates dialogue, email, and grammar table content with all three tracks, compiles it into one dark-themed HTML file, and delivers a mobile-friendly URL. ## Quick Start Create an interactive Japanese study HTML page with toggleable romaji and English tracks from my lesson notes and deploy it to GitHub for mobile viewing.
