+"""Resolve an app name to a Google Play link + stats, and measure saturation.
+
+Subcommands:
+  resolve "<name>"  -> top Play apps hit: package, play_url, rating, installs,
+                       last_updated, developer (1-2 links per candidate upstream).
+  count   "<query>" -> saturation: how many distinct apps + avg rating on the
+                       first Play search results page.
+
+Play search (play.google.com/store/search?q=...&c=apps&hl=en&gl=US) is
+server-rendered enough to grep details?id= links + star aria-labels. The details
+page carries rating/installs/updated in embedded ld+json (+ light regex), the
+same structure clone-app's scrape-play-store.py parses. Stdlib-only, no pip.
