## Analytics — identical model to the AE/Blender/DaVinci/Premiere addons.
## Posts to the BACKEND (/api/analytics/track) which holds the PostHog key, so the
## addon never ships a key (the old direct-to-PostHog path was a silent no-op
## because the key shipped empty). Body shape matches the desktop addons exactly:
##   { event, license_key: <distinct_id>, addon_name, properties{...} }
## distinct_id = account email -> guest_<machine_hash> -> anonymous (never a token).
