`UiScalar` was `Len` without the `leftover` weight, which is the separation canonical `main` already had as `Len` beside `LayoutLen` and this branch collapsed. It is needed back for the queued clamp: a cap may not contain a share, because a cap has to read the report a rule otherwise makes moot, and a share puts the container's division into the same equation -- two self-consistent assignments, which is the multiple-fixed-point failure generated seed 13 punished for orthogonal sizing. `min(report, cap)` is not a `LayoutLen` either: it is a sum of parts, and the smaller of two of them is not one. So `UiScalar` is `Len`, what was `Len` is `LayoutLen`, and the two say in their docs which is which: a `Len` is pixels plus a fraction of a box -- a position being the length from the box's start, which is why a span is two of them -- and a `LayoutLen` is a `Len` plus a claim only a container dividing its room can answer. `From<Len> for LayoutLen` is the one-way step between them. Names only; the shader's `UiScalar` is renamed with them. Checked: fmt, clippy, 105 tests, and `tabs`, `minimal`, `view`, `text` and `random` byte-identical at 1920x1200.
