/* Flomutredning.no -- shared foundation stylesheet.
   Distinct from skredgrunn.no's commercial layout: single-column,
   long-form reading design with a teal accent instead of skredgrunn's
   blue, and no hero/service-card patterns. Shares the same broad
   typography family (Space Grotesk / Public Sans) as a brand-family cue. */
