   Notice what's NOT here: no .card, no .title, no .price, no .btn, no
   .newsletter overrides. Those styles moved INTO the components' Shadow
   DOM (web-component.js). The global stylesheet only describes the page
   layout now — nothing a component owns can leak out, and nothing here
   can leak in. Compare with the native version's style.css.
