Reserva de instrumentos de laboratorio

/**
 * Benchlab instrument board: shared instruments and benches over one week, preparation included.
 *
 * Library: timeline with hidden nights, hour and day zoom levels, tree rows, disabled cells for
 * unavailable time, time-anchored event areas for the preparation, drag-to-book range selection,
 * drag/resize with overlap prevention, undo history, keyboard, and React content (row headers and
 * booking bars) through `super-scheduler/react-render`.
 * Application: how long each instrument prepares, where a booking may go, unavailable windows and
 * what a new booking needs in front of its run. Those rules live in ./rules and run in the callbacks.
