    description: Integrate the ODE forward until convergence (robust, default).
  newton:
    text: newton
    description: Use Newton's method to find the nearest fixed point.
  given:
    text: given
    description: Use the model's default initial values directly.
  from_branch:
    text: from_branch
    description: Start from a point on a previously computed branch.
  from_working_point:
    text: from_working_point
    description: Ramp a parameter quasi-statically (warm-start / from_previous) to
      a target value (see InitialState.ramp) and start from the endpoint state — reach
      a working point on the solution branch before the run.
  from_experiment:
    text: from_experiment
    description: Seed from the settled endpoint state of another already-run experiment
      in the study (referenced by InitialState.source_experiment). Reuses a working
      point that experiment already reached instead of recomputing it — the cross-experiment
      counterpart of from_working_point (which recomputes the ramp inline). source_point
      selects which settled point of the source run (default 'endpoint').
