/* Seven collections, one system (v2 adds Tools per playbook §V.6).
   Each collection gets exactly two signals: an accent — used as a 6px dot
   inside a neutral pill, and as a hairline where a rule is needed — and its
   eyebrow label. Nothing else changes: no per-collection type, layout,
   card shape or surface. */
