/**
 * Calendar-feed visibility e2e — proves the staged-booking gate holds on the
 * one path that needs no session at all: the public /api/feed/trip/:token.ics.
 *
 * tests/e2e/feeds.e2e.test.ts cannot cover this. It mocks buildTripCalendar and
 * never creates a reservations table, so it owns the calendar parts and the SQL
 * filter is invisible to it. This file runs the REAL CalendarService against a
 * real migrated SQLite instead, and asserts on the bytes a calendar client
 * would receive.
