What do design-system docs say about visual hierarchy and white space in layout (Apple HIG; Material)?
Apple's HIG Layout page (observed 2026-10-22) states hierarchy rules in plain prose: order by importance along reading order, align to signal relatedness, indent to signal subordination, group with negative space/containers/separators, and use progressive disclosure. It gives few numbers (tvOS 60/80 pt insets) and no white-space ratio. Material Design layout pages could not be read without JavaScript, so no Material rule is recorded.
