   FATURIM.COM — invoice.css
   Production invoice rendering. Identical across:
     1. Browser preview
     2. Downloaded PDF (via Save as PDF)
     3. Printed paper

   Rules:
   - Uses `mm` for the printable canvas (A4 = 210 × 297mm, 12mm margins)
   - Uses `pt` for font sizes (1pt = 1/72 inch — pixel-perfect)
   - Uses `<table>` layout for ALL multi-column sections (parties, items, totals)
     because flex/grid render inconsistently across print engines.
   - All colored elements force `print-color-adjust: exact`.
   - All number cells use `font-variant-numeric: tabular-nums` so digits align.
