<OvRangebar channels={data} />

The CSS is a separate import in every framework. A single element can be imported on its own instead of the whole kit: import 'overscan/src/ov-chart.js'

A reading is set as a PROPERTY, never an attribute. An attribute is a string, so an array cannot survive one and a null arrives as the word "null", which the protocol would read as a value rather than a dropout.

Every ov: event is bound with addEventListener. The colon has no declarative spelling in Svelte 5, where the on: directive is gone and "onov:commit" is not an identifier, nor in JSX. Vue can bind it.

The wrapper applies attributes ITSELF and hands the framework nothing but a ref. All three frameworks set a prop as a property when the name exists on the element, and this kit has 77 getter-only properties across 43 elements. Assigning one throws, and in React it does not degrade: the whole tree fails to render. 13 elements have a getter-only name that is also a real attribute (at, bearing, digits, duration, floor, fov, fresh, hold, lat, lon, period, pitch, range, ring, rings, span, step, sweep, sweeps, traces, value), which are the ones a reader would naturally pass in markup.
