- Off-viewport in-flow items (carousel slides beyond the right edge) keep
their per-viewport geometry deltas - they occupy layout and set track
cross-sizes even when not visible
- Height chains: single-viewport probe verdicts accepted for nodes that
only paint at one band; un-probed picture/object-fit:cover children
filling the parent count as height-deriving; a node whose own probe says
authored-explicit keeps its height at emission (twin of the flow guard)
- Symmetric authored-width circular guard in the walker (height-only
before), harvesting shadow-root adopted/style sheets for custom elements
- Auto margins only when width is genuinely content-constrained; gutter-
inset full-width blocks keep literal margins
- grid-template-rows: subgrid never dropped; variant-only subgrid intent
re-enters via partial-coverage escape; grid-item percentage widths bail
to auto (they resolve against the track, not the container)
- Banded raw-prop detection counts non-raw band overrides so a banded
bg-none reset isn't beaten by an inlined gradient
399 tests pass (13 new), typecheck clean.
