Canopy Part Title
A dense canopy of textured leaves sweeps across the frame with shallow depth of field, then parts to uncover the first headline; a second, depth-lifted batch carries the second headline past the camera. A handful of leaves stay behind on the type and keep a light breeze. Font, weight, size, letter spacing, leaf counts, sweep speed and the retained-leaf breeze are variables.
Composition id: canopy-part-title. Duration 12 s at 30 fps, 1920×1080.

Install
Install with npx hyperframes add canopy-part-title; by default the files above land under compositions/canopy-part-title/. Then mount the block from the host index.html:
<div
data-composition-id="canopy-part-title"
data-composition-src="compositions/canopy-part-title/canopy-part-title.html"
data-start="0"
data-duration="12"
data-track-index="1"
data-width="1920"
data-height="1080"
></div>Render with custom values by targeting the composition file directly:
npx --yes hyperframes@0.8.12 render 'compositions/canopy-part-title/canopy-part-title.html' --variables '{"headline1":"Understory","headline2":"Move slowly"}'Variables
Read at runtime via window.__hyperframes.getVariables(); declared on the composition root as data-composition-variables (single-quoted attribute, plain JSON).

Runtime contract
- One paused GSAP timeline registered as
window.__timelines["canopy-part-title"]. - Re-syncs on the
hf-seekCustomEvent; every frame is a closed-form function of time (seeded PRNG only, no rAF loops, no Date.now). - Renderer: three.js 0.170.0, GSAP 3.14.2, Canvas 2D, Post-processing, Seeded PRNG, Shadow maps. Budget roughly 350 MB per live instance; run one at a time.
- External runtime dependencies:

Editing rules (from the source project)
- Keep
data-composition-variablesa single-quoted attribute with plain"JSON. Never save it through Studio's Design panel. - Do not put
<canvas>in static markup; create it at runtime. - Keep every visual state a function of t; seek-safety is what makes the block renderable.
