/**
 * TCS Repair Forum — Print Stylesheet
 *
 * Activated only when the user clicks "Print / Save as PDF" on a single
 * checklist page. Generates a clean technician-friendly PDF with:
 *   - TCS Pune logo header (top of every page)
 *   - TCS watermark (faint, behind content)
 *   - Checklist title + board part number + difficulty
 *   - Step-by-step procedure (printable checkboxes)
 *   - TCS contact footer (bottom of every page)
 *   - Page numbers
 *
 * Tip for users: When the browser print dialog opens, select "Save as PDF"
 * as the destination to download a PDF instead of printing on paper.
