/*
 * Gradient / soft-UI design system for the administration panels.
 *
 * Colours were sampled from the supplied kit rather than eyeballed:
 * background #EDEDEF, gradient #FE9A3E → #FF404D, inactive surfaces #E8E9EB.
 * The kit is neumorphic, so shapes are lifted with a pair of shadows — light
 * from the top-left, shadow to the bottom-right — instead of a single drop.
 *
 * Layered on top of Bootstrap 5: the panels already use its classes, so this
 * restyles them instead of replacing the markup.
