/**
 * React Native overlay (NOT Skia) that floats `renderMarker` elements over the
 * Skia canvas, one per marker the consumer chooses to customize. Rendered as a
 * sibling of `<Canvas>` (like {@link AxisLabelOverlay}) so the elements can be
 * any RN view — including non-Skia effects (e.g. a glass `BlurView`) — and stay
 * crisp at native resolution instead of being rasterized into the marker atlas.
 *
 * The set of markers is mirrored to JS state via `markersSignature` (same as
 * `MarkerOverlay`); `renderMarker(marker, ctx)` is then called per marker on the
 * JS thread. Markers it returns an element for are excluded from the Skia atlas
 * upstream, so there's no double-draw.
 *
 * Custom views participate in {@link clusterMarkers}: a single per-frame
 * project+cluster over all markers feeds a `posById` map so co-located custom
 * views fan apart (or hide when their cluster collapses) in lockstep with the
 * atlas markers. `renderMarker` must return an element consistently for a given
 * id (it may restyle via `ctx`, but should not flip between element and `null`
 * based on `ctx.isGrouped`).
