+# A hand-written node, and the first thing in `Attribute::Optics`.
+#
+# Written, tested and unreferenced until now: `src/ops/vignetting.rs` has
+# existed with a full descriptor and a working polynomial, and without an entry
+# here it was never in `chain()` — so it reached no photograph and no panel.
+# This file is the whole of what was missing, which is the point of `ops/`
+# being the one place the pipeline's order is written down.
+id: vignetting
+order: 5

+attributes: [optics]
+rust: Vignetting
+
+why_rust: |
+  It carries a lens profile's `pa` coefficients, which are not parameters: they
+  come from the body and lens that took the photograph, not from the
+  photographer, and no `uniforms:` expression could produce them. The one
+  parameter that *is* theirs — the manual trim — is composed with `k1` in Rust,
+  because the profile and the trim have to reach the shader as a single
+  polynomial rather than as two the fragment would have to add up.
+
+placement: |
+  First in the chain, ahead of white balance and exposure.
+
+  Vignetting is what the lens did to the light before the sensor measured it,
+  so undoing it belongs with reading the file rather than with editing the
+  picture — everything downstream is then working on the frame the lens would
+  have delivered had it been even.
+
+  The ordering is load-bearing rather than tidy. Correcting a corner means
+  *dividing* by an attenuation below one, which pushes those pixels up: a fast
+  prime wide open needs about two stops there. Run after the tonal stages, that
+  recovery happens once the highlights have already been rolled off and
+  clipped, so it lifts values that no longer have anywhere to go and the
+  corners posterise instead of brightening. Run here, the headroom to hold them
+  still exists (ARCH §5.2).
+
+  Before distortion and chromatic aberration in intent, though those are
+  `lens::Warp`s rather than nodes and compose ahead of the fetch, so no `order:`
+  relates the two.
