Registers a before-each test hook.

# =============================================================================
# setup — Registers a before-each test hook.
# =============================================================================
#
# What this teaches:
#   • Testing setup hooks — `setup` registers a block that runs before each
#     test case (`test`) in the suite, ensuring shared state or side effects
#     are prepared
#   • Works with `teardown` (after-each) for paired setup/teardown
#
# Common mistakes:
#   • Confusing `setup` (setup) with `teardown` (teardown) — they run at opposite ends of each test.
#

# =============================================================================

# setup — before-each test hook
#
# GRAMMAR:
#   hookDecl :← 'setup' block
#
# EXPECTED OUTPUT:
#   No main — declaration or test-runner surface only.
#
# BACKEND:
#   declaration-only test hook (whitelist: setup/praepara.fab).
