/**
 * Central, extensible registry of known analytics event names. Adding a new
 * event elsewhere in the app never requires a migration - the database
 * column (collections/AnalyticsEvents.ts#eventName) is free-text - this
 * list exists purely so `track()` calls get autocomplete/type-checking and
 * the dashboard can show a nice German label instead of a raw event name.
 *
 * To add a new event: add one entry here, then call `track("your_event")`
 * anywhere in the app (see lib/analytics/client.ts).
