   Simon G. — product hub page (/simon-g, /en/simon-g)
   Extends the Groma site stylesheet. Reuses its tokens and its
   .section / .kicker / .lead / .grid-3 / .works / .work / .note /
   .btn / .contact-line classes. Adds only what those do not cover:
   the rules list, the plain tables, the plain lists, the role
   cards and the FAQ. Rectangles only — no radii, shadows, gradients.
