/* alan.bigsy.au - paper and ink theme.
 *
 * MOBILE FIRST: every rule outside a media query is the phone layout, and the media
 * queries only ever ADD room as the screen grows. There is no max-width query in this
 * file, so nothing here is a desktop layout being patched for small screens.
 *
 * Breakpoints: 560px (small tablet), 780px (tablet/desktop), 1080px (wide).
 * Class-based media queries only. No inline styles, no !important.
