Zero-GC seeded Simplex 2D/3D noise, unrolled FBM, ridged/billow multifractals, seamless loop, tileable field, curl2, curl3, domain warp, and bakeable heightfields + 3D scalar volumes. Deterministic via seeded permutation table.

Zero-dependency fullscreen ambient particle atmospheres. Twenty-three themed presets across five behaviors (EMBER, MIST, FLOAT, CHAOS, FALL). Parallax depth bands, pointer repel/attract, runtime theme & behavior registries, prefers-reduced-motion auto-deg

Zero-GC reactive throttle on @zakkster/lite-signal. Timer-based and rAF-aligned variants. Intent-guarded, synchronous emit, no per-change allocations.

Headless reactive data tables on @zakkster/lite-signal. CSS Grid (no <table>), pooled slots that never reparent, aria-activedescendant focus model. Zero-GC scroll path on @zakkster/lite-virtual. Grouping, aggregation, sticky group headers, and grand total

Zero-dependency game math primitives — lerp, clamp, damp, smoothDamp, smoothstep, easings, shortest-path angle interpolation, moveToward, wrap, repeat, pingpong, snap, deadzone. Tree-shakeable pure functions, <1KB gzipped.

Dev-mode forced-reflow detector. Patches layout-triggering getters, tracks DOM writes, flags read-after-write within the same task, attributes to call site. The #1 silent frame killer, made visible.

OKLCH color interpolation, multi-stop gradients, LUT baking, RGB bridges, sRGB gamut clamping, and CSS formatting for games and animations.

Zero-GC reactive debounce on @zakkster/lite-signal. Trailing and leading-edge variants. Intent-guarded, synchronous emit, no per-change allocations.

In-page visual debugger for @zakkster/lite-signal reactive graphs. A pure consumer of @zakkster/lite-devtools: live layered DAG view (SVG), node inspector, engine stats, lifecycle log, and DOT export. Non-self-instrumenting -- it never creates a signal, s

A headless particle engine with GC-free physics, lifecycle management, bounds culling, declarative emission zones, and seeded deterministic replay.

Zero-GC, data-oriented OKLCH color engine and WebGL/Canvas buffer pipeline.

Zero-GC halftone + color-separation kernels. SEP1 ships createSeparator/renderAM: an AM (clustered-dot) screen with per-ink angle rotation and moire-as-validation. Reuses lite-color-engine/remap nearest-in-OKLab pick so remap and separate agree by constru

Zero-GC 2D axis-aligned bounding box primitives. 22 ops on a flat Float32Array(4) [minX, minY, maxX, maxY], including packed 4xN batch ops; every op writes into a caller-provided out buffer — no per-frame allocation. ~230 lines, zero deps, ESM only.

Zero-GC persistent overlap events over a dynamic BVH (2D): turns a per-frame set of overlapping pairs into a per-frame delta -- enter / stay / exit -- with zero allocation per frame. Open-addressed Int32Array pair table, 1-bit alternating-tag mark-sweep.

Signal-native instanced primitive renderer: project ~1M points/quads/lines from reactive inputs, upload only what changed, draw in one instanced call. Deep-zoom precision via a GPU camera with double-emulated world coordinates. Zero-GC core + a browser We

Zero-GC, frame-rate scheduling for @zakkster/lite-signal. A single requestAnimationFrame loop, frameTime/frameDelta/frameCount plus fps/jank as reactive signals, rafEffect() with pre/normal/post priority lanes, auto-pause on hidden tabs, and lerp/damp int

Reactive-graph inspector for @zakkster/lite-signal. Non-perturbing introspection (peek + enumerator walks, never adds an observer), full auto-discovered DAG with diamond/convergence dedupe, live lifecycle feed, leak detector, DOT/tree renderers, and diff(

Zero-GC frame profiler: per-phase timing, deterministic counters, percentiles, frame classifier, .litecap binary capture, regression gating, and opt-in absolute-timeline capture for flame charts.

Wall-clock task scheduler over an @zakkster/lite-di-container topology: DI-constructed jobs registered as boot-locked per-id singletons, fired by index on an interval / every / cron-expr schedule. Zero allocation on the synchronous, non-promise tick path.

Zero-GC FinalizationRegistry helper. Shared disposal registry with unregister semantics, tag-based collection reporting, and error routing.
