Generating PDFs with React-PDF

CRITICAL REQUIREMENTS

1. Fonts MUST be local files - Remote font URLs (http/https) do NOT work. Always download fonts to local files before using them.
2. Wrap async code in IIFE - Top-level await causes errors. Always use (async () => { ... })() pattern.
3. Disable hyphenation for custom fonts - Custom fonts lack hyphenation dictionaries and may crash or break words incorrectly. Always call Font.registerHyphenationCallback((word) => [word]); after registering custom fonts.
