River Outfall Status Visualizer

Core Goal

• Convert one Excel workbook into:
• A scenario-aware river outfall status summary.
• A standalone HTML chart suitable for briefing and review.
• A reusable mock workbook that follows the same template.
• Keep the chart vertically truthful. Y values must always use real elevation.
• Allow horizontal zoom without resizing outfall symbols. Only the outfall anchor positions move with the river layout.
• Distinguish left-bank and right-bank outfalls with side-specific offset, connector direction, label placement, and legend.
