Overview

One step in the algorithm body.

‘kind` discriminates how the renderer formats this step:

"bind"        var ← expr_str                  (numbered)
"update"      var ← expr_str                  (numbered; same as bind, semantically distinct)
"loop_open"   for <expr_str> do               (numbered; indents subsequent steps)
"loop_close"  end for                         (numbered; outdents)
"return"      return var                      (numbered)
"comment"     ▷ note                          (un-numbered; for inline ▷ comments
                                               attached to the previous step)

‘shape` is the right-side annotation (`e ∈ R^T×D` etc.); blank skips it. `note` is an inline ▷ comment appended after the step.
