Subsequent Events [Abstract]
Subsequent Events	Subsequent Events The Company has evaluated subsequent events occurring through the date that these financial statements were issued, and determined the following subsequent event occurred that would require disclosure in these financial statements. Changes to U.S. Trade Policy On February 20, 2026, the U.S. Supreme Court issued a ruling striking down certain tariffs previously imposed under IEEPA. The ultimate availability, timing and amount of any potential refunds of such tariffs remain highly uncertain and are subject to further legal, regulatory and administrative developments. Following the Supreme Court’s decision, the Trump Administration announced its intention to invoke other laws to collect tariffs and announced new tariffs on imports from all countries, in addition to any existing non-IEEPA tariffs. There remains substantial uncertainty regarding the duration of existing and newly announced tariffs, potential changes or pauses to such tariffs, tariff levels and whether further additional tariffs or other retaliatory actions may be imposed, modified or suspended, and the impacts of such actions on the Company's business. The Company continues to monitor and evaluate these developments and assess their potential impact on the Company’s business, financial condition and results of operations.
