/* ── Month tile grid (shared component) ─────────────────────────────────────
   The whole-month picker service_period_controller.js builds its tiles into
   (shared/_month_grid): the invoice page's service-period popovers and the
   Management period filter. The popover and dropdown around it belong to the
   feature files (invoices.css, management.css). */
