Notes

• EPUB is recommended for articles — renders cleanly on e-ink with reflowable text
• The API is reverse-engineered and unofficial — endpoints may change with firmware updates
• Directory args accept paths (e.g., "Document/Books") or numeric IDs
• Some sites block scraping — if fetch fails, try a different URL or use a cached/saved page
