/* mail-server-monitor panel
 *
 * Layered on Bootstrap 5.3's color modes. Everything below is tokens + the
 * chart layer; Bootstrap supplies the grid, tables, forms and offcanvas.
 *
 * Chart colours are the validated categorical slots 1 and 2 (blue / orange),
 * which clear every CVD, normal-vision and contrast gate in both modes as an
 * adjacent pair. Failure tiles use single status colours, each paired with an
 * icon and a label so hue never carries the meaning alone.
