01 / 航路
Gale routes
Each corridor is timed to a gust window. Open it, gust it, or lock it — dispatch parcels straight from the chart.
Tap a route status to cycle OPEN → GUST → LOCKED.
02 / 海燕簿
Petrel log
Every bird, every wingbeat. Send them aloft, stamp their flights, rest them at the roost.

03 / 追跡
Post tracker
Stamp every parcel down the sky-road: nest → aloft → landfall → delivered. The gale sometimes takes its cut.
