What problem does it solve? ERP detail pages need printable document output (invoices, orders) that hides UI chrome and follows A4 print standards, plus a history view showing who changed what. This Skill provides the PrintLayout component rules and the AuditTrail component with its backing SQL procedure. ## Core Features & Use Cases - PrintLayout: Wraps document content with @media print rules — A4 page size, 15mm/20mm margins, repeated table headers, row break avoidance, and hiding navigation, buttons, and filters via the .print:hidden class. - AuditTrail: Renders a timeline of changes from audit.audit_log for any entity, backed by the administration.usp_GetAuditTrail stored procedure returning the last 100 actions with old and new values. - Use Case: On an invoice detail page, wrap the invoice content in PrintLayout so users can print a clean A4 document, and add an "Istoric" tab with AuditTrail to show the full change history. ## Quick Start Add a printable A4 layout and an audit history tab to my invoice detail page using PrintLayout and AuditTrail.
