Spacing System (the scale nobody owns)

Every gap uses one --space-* scale; relationships create composition, not arbitrary margins.

The decision order

1. Start with the 4px-base ladder 4/8/12/16/24/32/48/64/96px and --space-section: clamp(48px, 32px + 4vw, 96px) defaults. An alternate bounded scale needs brief and observed-hierarchy evidence.
2. Map attachment, control, task, group, region, and chapter to visibly different steps (roughly ≥1.5× between levels), or document a content-pressure exception.
3. Choose metronomic or intentional syncopated section rhythm from content pressure; explain it.
4. Use gap and one-direction logical margins; explain any arbitrary-margin exception.

Let content set the rhythm

Map operational tasks to compact predictability and editorial/narrative content to breathing room; retain one system and explain differing roles. Use the role map first:
