/**
 * CSS Masking (mask-image / mask-position / mask-repeat / mask-size).
 *
 * Value grammars are identical to their background counterparts, so the
 * background parsers are reused verbatim — including the addImage side
 * effect that requires `skipCache` on mask-image. -webkit-mask-* aliases
 * resolve to these properties in computed style.
 *
 * mask-mode/mask-clip/mask-origin/mask-composite are accepted by the browser
 * but not parsed here; rendering assumes the default alpha masking with
 * `add` layer compositing.
