DASHBOARD TAXONOMY HIERARCHY:

Level 1: Container (layout.css)
├── .module-content (OWNS 16px outer padding, overflow: hidden)
│   └── .tabbed-dashboard variant (padding: 0 - tabs own padding)

Level 2: Scroll Region (scroll-indicators.css)
├── .dashboard-content ← SCROLL REGION (non-tabbed dashboards)
├── .tab-content-container ← SCROLL REGION (tabbed workspaces)
│   
│   CONTRACT: Scroll regions are the ONLY vertical scroll points.
│   See scroll-indicators.css for the unified scroll behavior.

Level 3: Dashboard Structure
├── .dashboard-body (flex column + gap between sections)
│   ├── .dashboard-header (optional)
│   └── sections...

Level 4: Section Types  
├── .dashboard-section.kpis
├── .dashboard-section.data-table
├── .dashboard-section.chart-grid
├── .dashboard-section.activity-feed
└── .dashboard-section.actions

Level 5: Content Components
├── .section-header (.section-title + .section-subtitle + .section-actions)
├── .section-content (.metric-grid | .data-table | .card-grid | .activity-list)

Level 6: Atomic Elements
├── .metric-card (.metric-header + .metric-content)
├── .data-row (.data-label + .data-value + .data-status)  
├── .activity-item (.activity-header + .activity-content)

SPACING CONTRACT:
- .module-content owns 16px outer padding (defined in layout.css)
- .tabbed-dashboard overrides to padding: 0 (tabs handle their own)
- .dashboard-content is the SCROLL REGION (scroll behavior in scroll-indicators.css)
- .dashboard-body provides flex layout + 16px gap between sections
- Sections own internal padding (no margin)
- .section-content has NO padding (parent section owns it)
- Components own internal padding only
