/* Protein Intake Calculator — page-specific presentation.

   Shared shell, panels, hero (.rp-hero), stat tiles (.rp-tiles), FAQ, related cards and Cozy's
   pick come from styles.css and results.css. This file adds the weight presets, the range bar,
   the meal illustration, the source comparison, the label mini-tool and the neutral progress bar.
   Everything is scoped to .protein-page and uses the site's existing colour tokens, so both themes
   and the shared spacing system come for free. */
