* Advanced Blending: knockout, blend as group, transparency shapes, masks hide effects (part of #215) Blending Options > Advanced Blending now works end to end: - doc: AdvancedBlending on every layer (knockout none/shallow/deep, blend interior effects as group, blend clipped layers as group, transparency shapes layer, layer/vector mask hides effects), saved in .pcraft. - PSD and layered TIFF: knko, infx, clbl, tsly, lmgm, vmgm read into the model and written back (in place, or added when not at the defaults); the TIFF byte-order transcoder handles lmgm/vmgm as byte flags. - CPU compositor (compose/src/advanced.rs): shallow and deep knockouts (isolated groups and clipping groups stop a deep knockout), clipped layers blended individually, effects over the whole layer when Transparency Shapes is off, effects built from an unmasked copy when a mask hides them, interior effects under fill opacity. - GPU: documents using Advanced Blending fall back to the CPU compositor. - engine: layer.layerStyle.blendingOptions takes channels, knockout and the five switches; inspect reports them; Copy/Paste Layer Style carries them. - UI: the Blending Options page laid out like Photoshop's (General, Advanced Blending, Blend If with split sliders), translated. psd-tools corpus oracle 229 -> 236 (seven knockout files now pass; floor raised); other corpora and all round trips unchanged. Scorecard FILE-215-16 -> partial.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Undo damage: compare Layer.advanced in layer_pixels_equal; regenerate scorecard #810's exhaustive Layer destructure must classify the new advanced-blending field; it changes the composite, so it is compared.
