// Variadic heterogeneous type packs — follow-up #4 (runtime
// pack indexing).
//
// `args[<literal>]` substitutes through `pack_arg_nodes` (step
// 2a.B). But `args[<runtime_int>]` — a loop counter, an
// expression — falls through to the standard slice-indexing
// path, which fails because the pack-mono doesn't materialise
// the `args` slice. Output today: "unresolved 'args'".
//
// Pairs with follow-up #3: the same `[]Any` slice
// materialisation handles both `args` bare and `args[i]`
// runtime. Element type becomes `Any` (lossy on per-position
// types — that's the inherent trade-off of runtime indexing
// into a heterogeneous pack).
