// folder_cascade.js — measures the read-path of `GET /api/folders/{id}/resources?resource_types=folder`

// at four depths against a pre-seeded tree. Captures how listing cost scales
|
|
// with ltree depth (cf. `idx_folders_lpath` GiST index). Mid-depth samples
|
|
// (depth4, depth8) fall back to `deepest` when the seeded tree is shallower
|

// than that depth — see load-seed.rs::build_subtree.
