Landscape BoL was splitting the signature row down the middle — boxes half on page 1, half on page 2. Two complementary fixes: 1. **Per-element rule**: added `page-break-inside: avoid` + `break-inside: avoid` to `.sig-box` (both portrait + landscape styles) so an individual signature box can never split across pages. 2. **Wrapper rule**: introduced `.fp-keep-together` utility + wrapped the BoL's certification statement + signature row in it, so the whole "sign here" block moves to the next page as one unit if it doesn't fit. Also applied `page-break-inside: avoid` to `table tr` so cargo lines don't split mid-row either. Lives in shared `report_base_styles.xml` so any FP template that opts into `.fp-keep-together` benefits automatically. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
