// Shared visual chrome for keyboard-and-mouse-navigable items inside a panel.
// Contract: items must NOT read `containsMouse` for color/border. Mouse
// hover updates the panel's cursor state at the root; visuals derive from
// `hasCursor` / `current`. That's what guarantees a single highlight on
// screen at any time across both keyboard and mouse interaction.
//
// Cursor paint is always the shared hover-cursor fill plus optional
// hover-cursor border. `outline` remains as a compatibility flag for
// callers that used to request border-only rows, but slider rows still
// receive the same hover-cursor background as every other row.
