-- DreamStack Chained Composition — Layer 2: Master Dashboard
-- Receives the aggregated metrics (from Layer 1) AND mood (from Layer 0).
--
-- Architecture:
--   Counter ──┐
--   Clock  ───┤──► compose-metrics ──┐
--   Stats  ───┘    (Layer 1)         │
--                                    ├──► THIS APP (Layer 2)
--   Mood ────────────────────────────┘
--
-- This demonstrates:
--   1. Chained composition (3 → 1 → final)
--   2. Multiple layers of signal derivation
--   3. Mixing independently-sourced streams
--
-- Run with:
--   dreamstack build examples/compose-master.ds
