GridSizingKind

Remarks

⚠ This is deliberately not LayoutUnit, and the reason is fr. A flexible length is not a length: CSS Grid §7.2.3 says it resolves against the leftover space after every non-flexible track has taken its share, so it has no value at all until §12.7 runs. Adding it to LayoutUnit would put a unit into StyleLength that every flex-path Resolve would answer NaN for and no flex-path caller would know to ask about — a silent zero in the one place the store has no oracle. Grid gets its own vocabulary instead, which is the same reason it gets its own algorithm.

FitContent is a maximum only. CSS Grid §7.2.2 defines fit-content(x) as minmax(auto, max-content) with the result clamped by x, so it is stored as that clamp and never appears as a minimum.
