/* Peptigen Labs shop (customer pages only; the admin keeps app.css).
   A quiet apothecary counter with a few game-shop touches: item-slot cards, element sigils per category,
   option tiles, a numbered order path. Flat colour, no gradients except the hero heading text.
   CSP is strict (style-src 'self'), so no inline styles anywhere. */
