abstract: 'Provides a pipeline application programming interface (API) for Monte Carlo
  simulation-based sample-size planning in item response theory (IRT). Implements
  the 10-decision framework from Schroeders and Gnambs (2025) <https://doi.org/10.1177/25152459251314798>
  as a three-step workflow: specify the data-generating model with irt_design(), add
  study conditions with irt_study(), and run simulations with irt_simulate(). Supports
  one-parameter logistic (1PL), two-parameter logistic (2PL), and graded response
  models with missing-completely-at-random (MCAR), missing-at-random (MAR), booklet,
  and linking missingness mechanisms. Results include mean squared error (MSE), bias,
  root mean squared error (RMSE), standard error (SE), and coverage criteria with
  summary and plot methods.'
