Preserve SaaS card text wrapper geometry

[chubes4]

Summary

• Preserve class-owned SaaS/card text micro-wrappers as core/group wrappers instead of flattening them into paragraphs when their classes carry visual geometry semantics like badges, tags, prices, results, labels, names, and captions.
• Preserve max-width through the existing dimensions support mapper/serializer alongside min-height.
• Add PHP regression coverage for section/card max-width geometry and SaaS-style section/card label wrappers.

Root cause

SaaS sections and cards kept their outer grid/card classes, but text-only inner wrappers such as .tag, .tier-name, .tier-price, .use-case-result, and .featured-badge were flattened into paragraph/text shapes. The source CSS targets those wrapper classes for display, gap, padding, border radius, and card label geometry, so the transformed DOM lost selector addressability and produced high restyle_geometry / position_offset symptoms. Inline max-width was also not mapped through dimensions support, so section/card width constraints could be dropped when not class-owned.

Remaining SaaS Geometry Map

• Still high: SVG/map mockup elements are materialized differently, leaving many unmatched source SVG/text/g nodes.
• Still high: navigation/button anchors are intentionally out of scope for this pass.
• Remaining section/card issues: hover-state border-color/style deltas on integration/use-case/pricing cards; some inline text wrappers inside SVG-adjacent/product-sidebar areas still unmatched.
• Improved: section/card micro-wrapper geometry for badges/tags/labels/prices/results and max-width constraints.
