/**
 * A durable {@link AnalyticsService} that appends events to a table pikku owns.
 *
 * The destination of last resort, and the one a project gets for free: without
 * it an app that declares events either wires a vendor sink or watches them go
 * to the logger, and neither is somewhere you can answer a question from. It is
 * append-only by design — there is no read side here, because querying events
 * is what a warehouse or the console does with the rows, not what the ingest
 * path needs.
 *
 * Every column is text on every engine, so the same table reads the same
 * whether it was filled by a locally-run project or a deployed stage. Names are
 * written camelCase, as the declaration spells them, and `CamelCasePlugin`
 * turns both into the physical snake_case the migration created.
