/* Clearline Bookkeeping — professional-services concept. Calm navy and gold,
   serif display type, generous whitespace, straight edges on cards but soft
   rounded buttons. Meant to read as "trustworthy accountant", deliberately
   unlike the industrial trade site, the warm hospitality concepts, and the
   dark agency look of SiteMzansi itself. */
