- A failed readback mapping (e.g. device lost) now returns Unsupported,
so the caller falls back to the CPU compositor, instead of
expect("mapped readback buffer").
- Pipeline creation skips kernels without an entry point instead of
expect; resident/effect entries are looked up with let-else after the
insert; effect-program targets are Option instead of indexing +
expect; copies without a source are skipped; the planner returns
Unsupported instead of unreachable! for an adjustment layer.
- gpu denies unwrap/expect/panic/unimplemented/todo/unreachable.

CI's `cargo fmt --all -- --check` has failed on every run because the
repo had no rustfmt config and was never formatted. Use the same settings
as EffectCraft/FilmCraft (max_width 160, use_small_heuristics Max), which
also keeps the churn small. Formatting only; no code changes.

Model Blend If (This Layer / Underlying Layer ranges, split points) as
Layer::blend_if, read and write it as the PSD layer-record blending
ranges (previously parsed but dropped on export), save it in .pcraft,
render it in the CPU compositor (premultiplied mix = compositing at
k × alpha), fall back to the CPU on the GPU path, and drive it from
layer.layerStyle.blendingOptions {"blendIf": …}; document.inspect
reports it.

The non-legacy B/C was a linear scale that hard-clipped; Photoshop's modern
B/C is a pair of smooth curves that pin pure black and white. Reverse-
engineered from Photoshop 2026 ground truth (a 0..255 ramp pushed through the
app via executeAction BrgC, useLegacy=false):
- Contrast: symmetric cubic-Hermite S pivoting at 0.5 (end slope 1-c/128,
centre 1+c/128) -- near-exact, <=0.5/255 vs Photoshop.
- Brightness: line of slope 1.375^(b/50) rolled off to (1,1) by a v^P white
anchor -- close, approximate at the extremes (the real roll-off is a spline).
Applied brightness-then-contrast; matched in the wgsl compositor (mbright/
mcontrast) so GPU == CPU oracle (gpu parity 18/18). Golden tests pin both
curves to the captured Photoshop samples.
Corpus oracle: brightnesscontrast_grayscale.psd max error 0.478 -> 0.086
(bad px 91% -> 29%); 113 pass / 30 differ unchanged (no regressions).

Gradients/Patterns/Styles/Shapes/Tool Presets/Clone Source panels with
headless preset commands and a Custom Shape tool; Color card tabs match
Essentials. Character and Paragraph Styles (doc model, .pcraft, PSD style
sheets), Glyphs panel + type.insertText, Check Spelling (SCOWL-50 list).
Checkpoint also includes compiling in-progress work of the remaining agents.
