From 6cedd8410fa930facb4f48567fc9d86ffbb9865f Mon Sep 17 00:00:00 2001
From: Reviewer <reviewer@noveria.net>
Date: Fri, 12 Jun 2026 17:02:50 +0200
Subject: [PATCH] refactor(frontend): deduplicate CSS keyframes, unify types,
 extract format utils, add UI states, trim mock data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Remove duplicate @keyframes pulse-* from 3 component files (already in nexus-tokens.css)
- Rename AgentDetail → AgentDetailData in dashboard types to avoid collision with types/agent.ts
- Extract shared formatNumber/initials/formatTime to utils/format.ts
- Simplify FlowBoard: use agentStore modal/selection getters instead of duplicating local state
- Add error banner + empty state to IrisChat; add loading skeleton + error/empty states to TaskStrip
- Remove 105-line unused mockAgents array from useFlowLayout
- Reduce operations store fallbacks from hardcoded preview data to minimal safe defaults
- Update operations store tests to match lean fallback structure
- Net: -73 lines, cleaner imports, fewer magic strings
