/* RunCalc — Self-hosted fonts (task #27: font optimization)
 * Self-hosting eliminates 2 network roundtrips to fonts.gstatic.com.
 * Files downloaded from Google Fonts (same WOFF2 binaries, served from our CDN).
 * unicode-range subsetting: browser only downloads the file needed for the page's chars.
 * font-display: swap on all variants = no invisible text during load.
