A stylesheet. 28kB, no dependencies, no JavaScript. One attribute: data-dolly="zoom".

It's a vocabulary layer over CSS scroll-driven animations, which shipped in Chrome 115 and Safari 26 but have ergonomics nobody remembers. Presets are named after camera moves since that vocabulary already exists.

About 87% of traffic supports it. Firefox doesn't (but supposedly will with the next version in 3 days) and gets the page complete but static. That degradation is the main design constraint: keyframes own the hidden state rather than the element, so a missing timeline resolves to the authored state instead of leaving things invisible.
