`cargo fmt --check` is a required step and had drifted across 45 files. Most of
it arrived this week: several operations were written in parallel worktrees and
merged by hand, and a hand-merge resolves conflicts without ever running the
formatter over the result.
No behaviour changes — this is `cargo fmt --all` and nothing else, kept as its
own commit so the next reader can skip it wholesale rather than search it for
one that matters.

A test that cannot be run cannot be checked by running it, and a number
copied out of a test run agrees with whatever the code did on the day.
Each asserted kernel width, tolerance and overshoot bound now carries the
arithmetic that produces it -- the shorter edge, the sigma, the
truncation at two sigmas, and where the rounding falls -- so a reader can
verify the expectation against the recipe without a GPU or a compiler.
Also records the two places where a bound is a bound and not a
measurement: the tolerance in the frame-fraction test is exactly what
rounding a kernel to a whole pixel costs on the smallest frame it uses,
and the halo test's floor and ceiling bracket a peak derived from the
step, the soft limit and the midtone taper rather than from a run.

Checkpoint committed by the coordinator, not by the authoring agent: the
session hit its API limit mid-task and left this work uncommitted. Committed
so it survives, NOT because it is finished - expect failing tests and
half-applied changes. The agent resumes from here.
