Summary: AskYourPDF adds multi-document chat via Knowledge Base

Why It Matters: The product is shifting focus from single-file interactions to a broader "Knowledge Base" approach. This allows users to connect dots across many files at once rather than analyzing one PDF at a time.

What Changed:

• Replaced the "podcast generation" hero announcement with a "chat with multiple documents" feature.
• Added a new link to a "Knowledge Base" section (/documents).
• Updated the main headline to focus on saving study time and breaking down dense textbooks.
• Removed the specific "Scan QR code" text from the very bottom of the page.
• Cleaned up internal URLs by removing the "www" prefix.
