/* aiguide.se — built on Menodi V1's actual tokens, read out of the shipping site
   (Menodi/scripts/site_skin.py + the rendered homepage), not from a style guide.

   V1 is: white page, one purple action colour, SF Pro headings at weight ~550 with
   tight negative tracking (sans — NOT serif), solid 8px buttons, 14px cards, cool
   greys. An earlier pass here used a cream/mustard "warm editorial" system borrowed
   from an unrelated design skill; that was the wrong system and has been replaced. */
