   Website stylesheet — dark, in the colours of Courant's icon: the night (indigo → near black), the paper
   of the boat (lavender white), the waves (periwinkle) and the two sparkles (gold).
   Components of the sales pages come from Folia Files' site (same markup, same script).
   Motion: transform/opacity only for anything that loops; prefers-reduced-motion switches it off.
   Sections: tokens · base · layout · type · controls · nav · pricing · editions · FAQ · footer · pages ·
