/*
* Inter Variable — latin subset only, self-hosted from /public/fonts/.
* Preloaded in BaseLayout.astro <head>. font-display: optional avoids any
* FOUT/CLS contribution: if the font is not ready within ~100 ms the system
* font is used and Inter only swaps in on subsequent navigations (it's
* cached by then). With the preload tag the latin subset typically beats
* that window on first paint anyway.
