# Marcel gem may detect OGG Opus files as audio/opus instead of audio/ogg.
# This is problematic because WhatsApp Cloud API (and other services)
# expect audio/ogg for OGG container files with the Opus codec.
#
# This initializer patches ActiveStorage::Blob to normalize audio/opus → audio/ogg
# at identification time for .ogg files, preventing the wrong content_type from
# being persisted. Files with .opus extension are left as audio/opus since they
# are genuinely Opus-only files.
