   DiamondFlow — invoice-ui-upgrade.css
   Premium SaaS invoice UI upgrade layer.

   Fixes:
   · Currency symbol ₹ + en-IN formatting (via script.js patch)
   · Right-aligned numeric columns with monospace font
   · Misaligned table headers ↔ row values
   · Broken spacing & padding in item rows
   · Weak layout hierarchy in totals panel
   · Thin visual weight on grand total

   Load LAST — after all other CSS files.
   THIS FILE IS THE SOLE AUTHORITY on invoice grid layout.
   All other files (responsive.css, style.css) must NOT
   override grid-template-columns on .items-header / .item-row.
