/* The Protein Number — Slab's lead magnet. Three doors, one room.
   Generated pages: protein-to-lose-fat, protein-to-build-muscle,
   protein-on-a-glp1. See build/generate.py.

   This file is HAND-MAINTAINED, like styles.css and modal.js. The generator
   only ever writes .html.

   The page speaks THIS site's language — cream, ink rules, hard shadows,
   Space Grotesk. The one exception is the stack drawing, which carries Slab's
   six food-family colours: those are the product's actual output, not
   decoration, and the whole point of the page is that the answer looks like
   the app that gives it. */
