+Builds a structured daily board from scheduling data: appointments, gaps, confirmation flags, and summary.
+
+## What it does
+
+- Loads appointment data from fixture JSON files
+- Computes gaps between appointments (≥30 min)
+- Flags appointments needing client confirmation
+- Labels all output as `📋 FIXTURE DATA` — never silent fake live data
+- Outputs structured text or JSON
+
+## Quick start
+
+```bash
+# Text output (default)
+python skills/daily-board/scripts/build_board.py
+
+# JSON output
+python skills/daily-board/scripts/build_board.py --format json
+```
