CONFIG_TIERS =

Each tier holds candidate paths; the first found in a tier is used for that tier. Tiers are merged least-to-most-specific, so project settings override env-explicit, which override home/global settings. Settings absent from a more-specific tier are inherited from less-specific ones.

[
  # Tier 1 — home/global (least specific)

    -> { ENV["XDG_CONFIG_HOME"]&.then { |d| File.join(d, "rest_requestor", "config.yml") } },
    -> { File.join(Dir.home, ".config", "rest_requestor", "config.yml") },
    -> { File.join(Dir.home, ".rest_requestor_config.yml") }
  ],
  # Tier 2 — explicit path via environment variable
  [
    -> { (v = ENV["REST_REQUESTOR_CONFIG"]) && !v.empty? ? v : nil }
  ],
  # Tier 3 — project-local (most specific)
  [
