- Remove "Overview" nav link (index.sx IS the summary) - Rename "Demo" → "Examples" in nav and page title - Remove "Plan" and "Phase 2" from nav (all items done — status table remains in overview) - Add "Marshes" to nav (was missing, content already existed) - Add live event bridge demo island (data-sx-emit → signal via on-event) - Add event bridge section (#14) to examples page - Keep "demo" route as alias for backward compat Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
