The plan is ready for review. Here's a summary:

Goal: Add a pipeline progress indicator to the dashboard (Issue #192)

Approach: Compact progress bar in the pipelines table + ETA estimation in the detail panel

6 files to modify:

1. helpers.ts - Add computeStageProgress() and estimateTimeRemaining() helper functions
2. pipelines.ts - Add progress bar column to table rows + ETA in detail panel
3. index.html - Add "Progress" column header
4. styles.css - Progress bar CSS (reusing existing stat-bar pattern)
5. helpers.test.ts - Tests for new helpers
6. pipelines.test.ts - Tests for progress bar rendering

Key design decisions:

• Reuses existing stat-bar-track/fill CSS pattern for visual consistency
• Progress calculated from stagesDone.length / STAGES.length (data already available via WebSocket)
• ETA estimated from elapsed_time / stages_completed * stages_remaining
• Full ARIA accessibility (role="progressbar", aria-valuenow, aria-label)
• No new API calls needed - piggybacks on existing 2s WebSocket push
• Responsive mobile styles included
