# Microweber registers a lot of config at runtime (per-site overrides, dynamic
# module config, install-flow settings) inside service providers. Once Laravel
# has a compiled bootstrap/cache/config.php, those service providers run with a
# stale snapshot and the encrypter ends up with no valid APP_KEY -- the visible
# symptom is "Unsupported cipher or incorrect key length" / 500 on every MW
# route. We tested this on this stack: only config:cache breaks MW; route:cache,
# view:cache, and event:cache are all safe and provide the same boot-time win.
