## Description

A11ysaurio PDF Checker is a tool designed to help you ensure that the PDF documents
uploaded to your website meet accessibility standards (WCAG 2.1 and PDF/UA). It 
integrates directly into the WordPress Media Library, allowing you to analyze any
PDF with a single click without leaving your admin dashboard.

### Main Features:

 * **Automatic Analysis:** Instant detection of structural errors, missing language,
   missing titles, heading structure (H1-H6), and data tables.
 * **Native Integration:** Adds an analysis button to the list view and the details
   view of any PDF file within your media library.
 * **Validation History:** A central dashboard to see the accessibility status of
   all your analyzed PDFs at a glance.
 * **Total Privacy:** All PDF parsing and analysis is performed locally in your 
   web browser. The document is never uploaded to external third-party servers, 
   ensuring the confidentiality of your data.
 * **Keyboard and Screen Reader Support:** The review interface itself is built 
   following good accessibility practices.
