Two rulings made during Task 4 execution (see ledger): the early-refresh
headroom now scales with token TTL instead of a flat 60s (a flat skew made
the test's short-TTL token already "expired" the instant it was cached),
and every scratch script that requires config/config.js now sets NODE_ENV
before requiring it (the app's real entrypoint always resolves this via
config/init first; the plan's scratch scripts had bypassed that).
