/*
 * Aiko student tour overlay.
 *
 * Layer note: joins @layer legacy like account-onboarding.css so it sits in
 * the cascade declared by aios-layers.css instead of outranking every layer.
 * The dim comes from the spotlight's outward box-shadow, which punches a hole
 * around the highlighted element; the scrim only blocks clicks, and takes the
 * dim itself on the two steps that have no anchor.
