duplicate_animation

RECOMMENDED PRIMARY MOTION PRIMITIVE: Adds an animation object with multi-track keyframes. Preferred over heavy effects for 60fps performance and zero filter memory bloat.

Adds procedural motion to a normal object: `function animate(t, o, params, ctx)` runs every frame; set o.x/o.y/o.rotation/o.skewX/o.skewY (added), o.scale/o.scaleX/o.scaleY/o.opacity (multiplied), o.text, o.color. Offsets apply to the object's static transform and override its keyframed transform, so to combine with keyframes put the keyframes on a parent Frame (not a Group, which re-centres on its moving child). Use for orbits, wobble, noise drift, counters and seamless loops while the object stays editable.

Attaches drawing code to an object: `function render(ctx, env)` runs every frame and paints into the object's box (origin at its centre; env has width, height, time, params, inputs, pointer). Use for generative motion: particles, flow fields, metaballs, procedural type, 3D projection, textures. Put full-bleed pieces on an artboard-sized Rectangle. Code is syntax-checked and linted for minifier and determinism problems. See get_motion_skill { topic: 'effect-code' }.

Adds a visual effect to an object (blur, backdropBlur, glow, dropShadow, innerShadow, etc.). ⚠️ PERFORMANCE & MEMORY NOTICE: Visual effects cause heavy GPU/canvas rasterization filter passes and high memory consumption during animation. NEVER use effects as a substitute for motion, states, or interactions. Always build dynamic behaviors using (1) Animations (animate_properties, create_timeline), (2) State Variables (add_input, bind_variable), and (3) Project / Interaction Rules (add_object_interaction, setup_project_rules). Use add_effect sparingly for subtle static aesthetic styling only.
