PowPow Publisher

Publish posts/travelogues to PowPow (global.powpow.online), and create digital humans pinned to the public map. Triggers when the user wants to publish travel content (photos / travelogue / trip stories) to PowPow, e.g. "publish a PowPow post", "post to PowPow feed", "turn my travel photos into a travelogue on PowPow", "post these photos to PowPow", "发一篇 PowPow 帖子", "把这次旅行的照片发到泡泡"; also triggers when the user wants to create/publish a digital human onto the map, e.g. "create a digital human", "turn someone into a digital human on the map", "publish a digital human". Requires a PowPow account (register first if none). Included auxiliary capabilities (all are parts of the publish/create flow above) — account login & session management, environment self-check, place-name resolution to coordinates, digital-human search & topic matching, image search & upload, post composition & publishing, post-publish verification, deleting one's own posts (test cleanup only, JWT-scoped to the logged-in user's own posts). Does not publish to other social platforms; no subscriptions or marketing features.
