   csn.liot.se — Fribeloppet
   Bygger på liot-style (designtokens från register.liot.se).

   Dokumenterade avsteg från profilen:
   1. --ai-yellow används INTE alls här. Inget innehåll är
      AI-genererat — alla siffror kommer från CSN:s egna tabeller.
      Varningar/status löses därför med form (fylld vs streckad
      ram, invertering) i stället för färg, precis som profilen
      föreskriver.
   2. Ett extra lager i rutnätet: --hair, en 1px-linje som ligger
      mellan --border och --border-strong, för de täta
      sifferraderna i beloppstabellerna.
