/* ===========================================================================
   EME Showroom — landing page styles.

   Hand-authored to replace the Tailwind CDN build. That CDN ships a JavaScript
   compiler that has to download and run before the page has any styling at
   all; in an exhibition hall — hundreds of phones sharing congested wifi — that
   is seconds of unstyled text, or a blank screen. This file is a few KB, is
   render-blocking for a single round trip, and cannot fail halfway.

   Design tokens are carried over unchanged from the original Tailwind config,
   so the page looks exactly as it was designed.
   ========================================================================= */

/* ---------------------------------------------------------------------------
   Poppins, self-hosted.

   Subset to Latin and converted to WOFF2 from the TTFs already in the repo
   (Documents/Expert/Fonts/Poppins, OFL — licence copied into fonts/). 156 KB of
   TTF becomes 7.5 KB per weight, and being same-origin there is no third-party
   DNS lookup or TLS handshake to stall on hall wifi — which is exactly the
   moment a webfont from a CDN would leave the page in fallback type.

   Only the three weights the page actually uses are shipped: 300, 400, 600.
