    onLongPress durationMs? slopPx?
    onLongPress: (clientX: number, clientY: number, event: PointerEvent) => boolean

    Called once at the hold threshold; return true when it opened an action.

    durationMs?: number

    Hold duration in ms (default 500 — the platforms' own long-press timing).

    slopPx?: number

    Movement (CSS px) that cancels the press — a finger that travelled this far is dragging, not holding (default 12, the touch click slop).
