/* ============================================================================
   Lancalot — My Calendar multi-calendar chrome (#11–#13)
   ----------------------------------------------------------------------------
   ADDITIVE ONLY. Loaded after styles.css. Reuses .calendar / .calendar__corner /
   __head / __name / __body / .booking-layer / .booking-item / day headers /
   weekend bands. Adds: the stacked multi-row Timeline grid, per-calendar rail
   chrome (name / public-private / delete), the "+ New calendar" affordance, the
   Month rail selector, the empty state, and the create/confirm modal. No token
   or core class is overridden.
