| Expense Example Narrative [Text Block] | This Example is intended to help you compare the costs of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, regardless of whether or not you sell your shares at the end of such periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses (as described above) remain the same.

| Portfolio Turnover [Heading] | <span style="color:#000000;font-family:Times New Roman;font-size:10pt;font-weight:bold;">Portfolio Turnover</span> |
| Portfolio Turnover [Text Block] | The Fund pays transaction costs, such as commissions, when it buys and sells investments (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. For the fiscal period ended December 31, 2024, which includes the period in which the Predecessor Fund was in operation, the Fund’s portfolio turnover was 522%. The Predecessor Fund’s portfolio turnover rate during the period in which the Predecessor Fund was in operation reflects transactions made in preparation for the Predecessor Fund’s reorganization with and into the Fund and is not representative of the Fund’s expected portfolio turnover rate. Based on the Fund’s portfolio of investments, the Fund anticipates having a modest portfolio turnover rate. Portfolio turnover will not be a limiting factor should the Adviser deem it advisable to purchase or sell securities. |
