/**
 * Regression test view for issue #212, in the direction the original bug hit: a calendar-level
 * {@code setOption(EDITABLE, false)} must actually prevent entries from being draggable, even
 * when those entries were never explicitly configured (no {@code setEditable(...)} call). Before
 * #212, every entry's implicit {@code editable: true} default was serialized and overrode the
 * calendar-level option.
 * <p>
 * The view renders two entries, neither of which calls {@code setEditable}. Playwright verifies
 * that FC does <b>not</b> add the {@code fc-event-draggable} class to their rendered elements.
 * <p>
 * Route: /test/calendar-editable-false
