-- Showcase the calog pubsub library within a single Lua context: two handlers
-- subscribe to the "news" topic, a publish delivers to both (count 2), then one
-- handler unsubscribes and a second publish delivers to just one (count 1).
-- A short timer defers the exit so all deliveries land first.
-- Run: bin/calog examples/scripts/libraries/pubsub.lua
