 * `<before>`, `<after>`, the per-card and per-line variants and the two
 * delimiters emit text around the generated rows. Interpolation DOES run there —
 * a `${{Name}}` reads the row the fixture stands beside, which is what lets a
 * record put its own fields around a nested list. A GENERATOR does not, and
 * nothing enforced that, so a
 * `<gen>` inside one was accepted in silence and emitted a CONSTANT:
 * `value="500..999"` produced `500` on every card and under every seed. A
 * constant that looks like a generated value is worse than either honouring the
 * generator or refusing it, and the identical tag inside `<block><line>` has
 * always been a hard error. Same rule, same code (TDC131).
