/* Ember Recipes marketing site — shared design system.
 *
 * Built from docs/build-plans/landing-page-redesign.md §7. Shared by index.html, /en/index.html and
 * install-windows.html so the three cannot drift; legal.css keeps the older privacy/terms pages.
 *
 * FONTS — deliberately the system stack for now. §7.3 specifies self-hosted Fraunces + Inter as a
 * ~150-250KB .woff2 subset; the fonts actually in the repo are 1.2MB of variable .ttf (Inter alone
 * is 856KB), which is the wrong trade for a page whose whole job happens in the first two seconds.
 * Subsetting them is an asset task like the screenshots — the @font-face block below is written and
 * ready, and needs only the four files from §8 dropping into /assets/fonts/.
 *
