/*
 * webviglabs.com
 *
 * One stylesheet, no framework. Written mobile first:
 *   - base rules:      below 768px (mobile artboard M5-0, 390px)
 *   - min-width 768px:  tablet, desktop structure with 48px gutters
 *   - min-width 900px:  lab tiles go two-up
 *   - min-width 1200px: desktop artboard A6-0, 1440px
 *
 * Content width. Every block that spans the page sets
 *   padding-inline: var(--pad)
 * where --pad is max(gutter, (100% - 1200px) / 2). Text stays in a centred
 * 1200px column (120px gutters at 1440px) while tile backgrounds run full
 * bleed. --pad holds a percentage, so it resolves against whichever element
 * uses it; it is only used on elements whose containing block is the full
 * page width.
 *
 * Sections follow page order.
