/*
 * IntelliSys - Main Stylesheet
 *
 * Mobile first: every component is styled for the narrowest screen, then enhanced at wider
 * breakpoints, and each component keeps its responsive rules right next to it. Type and spacing
 * are fluid tokens, so most components need no breakpoints at all; the few that change layout use
 * these, in em so they also follow the visitor's own font-size setting and browser zoom:
 *
 *   36em  ( 576px)  small tablets and large phones in landscape
 *   48em  ( 768px)  tablets
 *   62em  ( 992px)  laptops: full navigation, side-by-side layouts
 *   75em  (1200px)  wide screens
 *
 * Above a 1440x900 laptop the root font size grows with the screen, so a 4K monitor or a
 * zoomed-out window shows the same layout as the laptop, only larger.
 *
 * Sections: 1 fonts and tokens, 2 base, 3 layout, 4 components (in page order), 5 utilities, 6 motion.
