    disclosure; a non-expandable identity cell must otherwise expose its
    complete value without requiring hover. Default data rows stay single-line
    so scan density and row rhythm are not traded for automatic text wrapping.
+   When a platform table row itself owns that keyboard- and touch-operable
+   disclosure, `SummaryRowActionButton` removes the redundant visible chevron
+   below the shared mobile breakpoint while preserving the button for screen
+   readers and revealing it on keyboard focus. `PlatformResourceDetailToggleButton`
+   applies that policy to provider-native platform tables, and workload rows
+   opt in only while their compact row remains the disclosure target. Rows
+   whose click action does something other than expand details must keep a
+   visible disclosure control.
    They must not rely on a global rule that reveals
    every hidden column: phone priority remains source-specific because state, capacity,
    freshness, and recovery posture do not carry equal value for every resource
