• Interactive elements have contentDescription via semantics
• Decorative elements: Modifier.semantics { invisibleToUser() }
• Related elements: Modifier.semantics(mergeDescendants = true)
• contentDescription is localized
• Use Role (e.g., Role.Button, Role.Switch, Role.Checkbox) via semantics { role = Role.Button }
• Provide stateDescription for toggles/switches (e.g., "On", "Checked")
• Mark headings with semantics { heading() }
• Use onClickLabel for custom action descriptions
• Control traversal order with isTraversalGroup and traversalIndex when default order is insufficient
• Override defaults with clearAndSetSemantics { ... } for complex custom components
