Income Tax Disclosure [Abstract]
Income Taxes	5. Income Taxes The Company recorded income tax expense of $108,205 in the 13-week period ended September 27, 2025, compared to income tax expense of $87,139 in the 13-week period ended September 28, 2024. The effective tax rate was 21.2% in the third quarter of 2025, compared to 17.9% in the third quarter of 2024. The increase in the effective tax rate in the current quarter was primarily driven by the U.S. tax legislation enacted during the current quarter, which, among other things, changed capitalization requirements of certain research and development costs, resulting in a year-to-date adjustment due to a decrease in certain expected U.S. tax deductions and credits. The Company recorded income tax expense of $243,943 in the 39-week period ended September 27, 2025, compared to income tax expense of $203,560 in the 39-week period ended September 28, 2024. The effective tax rate was 17.7% in the first three quarters of 2025, compared to 17.3% in the first three quarters of 2024. The increase in the effective tax rate in the current period was primarily driven by the U.S. tax legislation enacted during the current quarter, which, among other things, changed capitalization requirements of certain research and development costs, resulting in a decrease in certain expected U.S. tax deductions and credits.
