 ### Requirement: Optional single-row Grid details presentation
 The Vaadin collection Grid adapter SHALL support an optional toolkit-neutral row-details descriptor while leaving expansion authority, effective preview templates, row contexts, and domain behavior with the owning `<cw-collection>`.
 The adapter MUST keep at most one details item open and MUST preserve native fallback equivalence.
+Its preview disclosure MUST use the same appropriately sized decorative direction indicator and state-driven presentation as the native collection disclosure.
 
 #### Scenario: Grid item has an effective preview
 - **WHEN** the collection projects a Grid item with a current safe preview descriptor
 - **THEN** the Grid renders a compact leading disclosure control with row-title-based accessible naming
+- **AND** the disclosure contains the shared non-focusable, assistive-technology-hidden SVG indicator instead of a Grid-specific text glyph
