/*
 * MKS Knowledge Base Pro
 *
 * Every rule is scoped under .mks-knowledge-base-pro so nothing here can leak
 * into the rest of the CRM. The palette is deliberately neutral: Perfex lets
 * each installation pick its own accent colour, so hard-coding a brand hue here
 * would fight whatever theme the client is running. Colour is spent in exactly
 * one place, the visibility chips, because who can see an article is the single
 * thing this module exists to make obvious at a glance.
