Recipe 6 — Dispatch / Pattern

What: Split a list into A/B outputs using a boolean pattern — checkerboards, alternation, skip-N.

Zone Map:

[List_in][Pattern] → [Dispatch] ──→ [Swatch_A][Preview_A]
                                   └─→ [Swatch_B][Preview_B]

Pipeline

[Input List]        [Pattern: "true;false" panel]
(e.g. SubSrf.S)        (alternating toggle)
       │                     │
       └─────────────────────┤
                             ▼
                        [Dispatch]
                          │    │
              ┌───────────┘    └───────────┐
              ▼                           ▼
      (items where true)           (items where false)
              │                           │
              ▼                           ▼
     [Swatch: colour]  → [CustomPreview]   [Swatch: colour]  → [CustomPreview]
          (A)                              (B)

Common patterns: true;false = ABAB · true;true;false;false = AABB pairs · true;false;false;false = every 4th

Output

Two lists partitioned by the pattern.
