/* Events Calendar — standalone static site (Vercel). No build step, no deps.
 *
 * This is an APP, not a document: the calendar owns exactly one viewport and
 * nothing scrolls except the detail panel. That constraint drives most of what
 * follows — the week rows share the leftover height so a month always fits, and
 * event bars are positioned over the day cells so one event can cross days. */
