* perf(scene-graph): give imported nodes the shape every node shares createDefaultNode had no default for booleanOperation, and the .fig importer sets that key on every node. A key outside an object's initial shape turns it into a JavaScriptCore dictionary, so every imported node had its own structure and dictionary property storage. Fully loading material3.fig took 3.7 GB RSS in Bun; with the default it takes 2.8 GB, with 0.5 GB less JS heap and 0.46 GB less memory outside it. V8 keeps these objects fast either way. The defaults now must name every SceneNode field, which the compiler enforces, and a test checks that imported nodes carry exactly the default fields. booleanOperation states the explicit undefined the importer already stores. * fix(scene-graph): require booleanOperation and compare node keys in order Every SceneNode field is required except booleanOperation, so a typed producer could still omit it and build a node with a different shape. It is now required, with undefined still meaning no operation. The node-shape test compares keys in insertion order, since JavaScriptCore lays out the same keys added in another order as a different shape. The changelog entry no longer quotes the Bun measurement as figures for the macOS app and Safari, and records the type change as breaking. |
