The moment an entity gains Disabled (spec section 0: runtime enable/disable via bind-disabled), strip every live interaction state from it:

• Hovered / Pressed are removed (with their transient tween components) - the hover tint / press tint end immediately, and a pending release will not click (dispatch_clicks requires Pressed). The tinted fill is let go of at once, so the :disabled swap lands on the true idle style.
• Keyboard focus moves to the next focusable in tab order (same (TabIndex, DocumentOrder) ordering cycle_focus_on_tab uses, wrapping; hidden and disabled entities skipped), or clears when the disabled entity was the only focusable. The FocusVisible marker travels with the focus if it was present.
