`cursor` added `px` and `rel` by hand where the placing loop below now says
`fixed += len.without_leftover()` -- the same sum, one of them named. And
`let along = total` shadowed the closure that makes a span along the row,
two meanings for one word in one function; the local said nothing `total`
did not.
A scroll's draw writes `amt` and `snap_end`, so a second draw at another
viewport reads what the first wrote. Warm still matches cold because
re-clamping is idempotent, but nothing said so and nothing checked it: the
seed scans build scrolls and never scroll them. The test scrolls four
distances, one past the end, and widens.
