feat(visual): implement the slice 4e procedural systems and behaviors
The normative coherent noise of 18.7 (ordered gradients, a 255-sample Fisher-Yates permutation, octave normalization, and curl as the explicit perpendicular of the potential's gradient, with published tolerances), the nine distributions with their normative draw-order table, all seventeen behaviors with their field contracts and the accumulating-versus-fresh split, component expansion independent of group nesting depth, particles, emitters, repeaters, trails, and links. Traces 1 through 19 of 18.10 are automated. The renderer core this builds on is corrected here rather than separately, because 4e is what exercises it: the production render path now passes a real compositing surface factory, so a masked group or a non-opaque layer composites instead of throwing and permanently deactivating the visual subsystem; system-level `behaviors` arrays run `validateBehaviors` at import with field context, so the six classes of invalid document that used to fail at activation now fail where an author can see them; velocity-accumulating behaviors integrate on object and repeater hosts; `morph` guards both sides of the z delta rather than poisoning perspective projection with NaN; `face-motion` initializes its follow state lazily and holds the previous rotation at zero velocity; a `ring` with equal start and end angles draws nothing instead of a radial spoke; a resolved non-integer creation count raises ERR_TYPE_MISMATCH at the boundary instead of being rounded; boolean leaves are type-checked; per-type required fields and the static half of the unbounded-emission rule are enforced at import; and a repeater rejects the emitter-only fields 18.5 says it has none of. A duration is now the authored literal or a non-negative finite number already in milliseconds, resolving the one design question the review triage left open. Runtime, validator, and specification agree on it. A guard test asserts that no two bundled modules declare the same top-level identifier: the bundler concatenates into one scope, so a private helper name collision is a SyntaxError in the artifact while every unit test still passes.

feat(visual): implement the slice 4d renderer core
The first visual code that draws. Sections 17.4 through 17.14 are implemented against Format Specification revision 0.8, and the standalone artifact now has a stage canvas that renders a declared scene. The renderer is split so that the automated traces of 17.16 can run without a display, which is what those traces require. visual-engine.js resolves an exhibit's objects once at their instantiation boundary, composes the scene-to-device chain, sorts by depth, applies fog and the compositing order, and emits a **frame plan** in device pixels; visual-canvas2d.js turns a plan into drawing calls. A plan carries the numeric oracles the traces ask for - a known scene point at a known display point, a perspective factor, a fog fraction, a sort order - where a canvas carries only pixels. visual-math.js implements the affine matrices, the normative local transform of 17.11, the directed arc sweep of 17.9 with its bound checked before normalization, and section 2 color parsing with the fog and ramp arithmetic of 17.6 and 18.2. Colors outside the four documented forms are ERR_TYPE_MISMATCH: exact components are what make per-object fog renderer-independent. visual-geometry.js reduces all fourteen primitives to subpaths of lines and cubic Beziers, so an affine map carries geometry exactly rather than approximately. It implements the local extents and anchors of 17.9 - a rectangle anchored top-left, circular primitives centered - the uniform cardinal form of catmull-rom with its open-duplication and closed-wrap index rules, the straight closing segment of a closed bezier spline, and endpoint-parameterized elliptical arcs. The composition chain of 19.3 is implemented as written: the fit matrix carries the contain and cover centering offsets, the camera center is mapped into CSS coordinates before the translation is formed, perspective acts about the projection center, and the device-pixel multiplier is applied exactly once and drops below 1 on a display larger than 4096. Scalars with no axis - stroke widths, radii, dash lengths - take the single uniform factor g, so a nonuniform stretch never distorts a stroke. Depth follows 17.6: effective depth accumulates z and translate.z up the tree, sortable units order farthest-first with the documented tie-break, a point's own z projects that point without making it a sortable unit, and an object at or behind the eye is culled with no diagnostic. Compositing follows 17.12: opacity multiplies down the tree while layer opacity applies once at the layer, and the sixteen buffer allocations per frame are granted nearest-first so refusals fall on the far content, each diagnosed under the 19.5 cadence rather than omitted silently. visual-validation.js gains the object tree: the fifteen object types and their declared fields, no `id` and no `layer` on an object, a declared fill on a stroke-only primitive, a mask only on a group and only naming its own child, path legality, spline modes and point counts, gradient stop order, and every authoring limit of 19.5 that applies to a drawn object. While implementing V10 I corrected the buffer-accounting rule I had written into 17.12: counting buffers as concurrently live made 19.5's farthest-first shedding nearly unreachable, since group nesting is already capped at 8. The rule is now 16 allocations per frame, which is the per-frame reading "pass budget" has carried since 17.5 first used it. The arc-sweep prose is likewise corrected to normalize the signed delta, so 350 -> 10 clockwise is the 20-degree sweep the text always claimed rather than 340 the long way round. test/phase4-renderer.test.mjs adds 22 tests covering traces 1 through 13 of 17.16 plus buffer shedding and the backend's call order. npm test goes from 131 to 153 passing. Traces 15 and 16 remain user-observed, and no procedural system, automation track, or post-effect executes yet - 4e and 4f own those.
