/**
 * Create a `PropertyManager` for CSS `@property` registrations.
 *
 * This manager stores normalized registrations keyed by custom property name
 * and can render either a single `@property` block or the full set.
 *
 * Design notes:
 * - Inputs are normalized through `coerce_atprop_input()` so internal state is
 *   canonical (stable comparisons, stable rendering).
 * - `onChange()` is invoked whenever registrations *meaningfully* change, so a
 *   caller (typically a higher-level CSS manager) can re-render/rebuild a style
 *   sheet snapshot.
 * - Rendering is deterministic: `renderAll()` sorts names to keep output stable
 *   across runs and avoid noisy diffs.
 *
 * @param args
 *   Construction options.
 *
 * @param args.onChange
 *   Callback invoked when the manager’s rendered output should be considered
 *   dirty (e.g., after register/unregister/batch updates).
 *
 * @returns
 *   A `PropertyManager` with register/unregister/query and render capabilities.
