Only rel doubles: apply_rest turns rest into the whole box and px
coincides. Aligned and Scroll honour a hint the same way Span does, so
all three double it. Also corrects the note about a fractional hairline,
which fails because a fraction is a fraction of its own box rather than
through any rounding, and records that a span whose shares run out walks
its children backwards instead of overflowing forward.

The text reference render is not byte-identical after all: a declared
rel or rest length is applied by the span and then again inside SetSize,
so .width(rel(0.5)) draws its child at a quarter. Also replaces the
example that measured one-pixel lines with what the tests now say, since
a span short of room overlaps its fixed lengths rather than collapsing
them.

The tabs difference does not reproduce at f61e893 against upstream/main
built in its own worktree, so nothing is waiting on a decision. Records
the instruction counts, frame times and memory taken today rather than
mid-branch, and what a one-pixel line and a one-pixel gap do under the
chain, which is the question the pixel difference was really about.

A fresh session had no way to learn the handoff existed: AGENTS.md named
only docs/PLAN.md, and the filename tied the document to one piece of work.
