// ArrayBuffer and SharedArrayBuffer inspection: Node's formatArrayBuffer
// `[Uint8Contents]: <hex pairs>` entry (the first 100 bytes, then
// `... N more byte(s)`) plus the byteLength entry inside the class
// braces, breaking onto lines past the 80-column budget, nested in
// objects and arrays, `[ArrayBuffer]` beyond the depth limit, and the
// backing buffer of a non-byte typed array.
