/*
 * Cuebots product site. Plain CSS; light, dark or Auto (macOS) from the footer's switch.
 *
 * Typography follows developer.apple.com's type scale (sizes, line heights, weights and its two breakpoints at
 * 1068px and 734px), with SF Pro Display from 19px up and SF Pro Text below. Letter spacing is never negative: where
 * Apple tightens, this page keeps `normal`; Apple's small positive tracking at narrow widths is kept. The brand and
 * every heading are set in Cue Sans, the face made for Cuebots; body copy stays SF Pro.
 */

 * Cue Sans, served as WOFF2 built from the OTFs beside them by scripts/180_build_site_fonts.py; a browser fetches only
 * the weights the page uses. Bump `?v=` whenever the files are rebuilt: the names stay the same, and a cached copy of
 * an older build would otherwise keep showing.
