   0.12.6 (patched qt): @page size and margin are ignored outright -- a Letter stylesheet

  /* The figures, the reason for them and the footer are ONE UNIT. page-break-inside on each
     block separately keeps each block whole and says nothing about keeping them together, so
     the N/A tax lines could stay on sheet 1 while the reason explaining them lands alone on
     sheet 2. The chain of page-break-before avoids is what binds them.

     .inv-foot needs its own avoid, and only since 2026-08-25: before the reason line existed,
     .inv-sum's page-break-after was the whole chain. The reason line now sits BETWEEN the
     summary and the footer, so that after-avoid no longer reaches .inv-foot -- and the footer
     carries the TPS/TVQ registration numbers. Without this the footer can orphan onto its own
     sheet, and ONLY on an invoice where relief was claimed.

     page-break-before is the property app/services/pdf/renderer.rb records as measured working
     against wkhtmltopdf; page-break-after is not, which is the second reason not to lean on it. */
