/*
 * The Joinery site's own rules: its layout, type and brand. Everything a component on the page
 * draws comes from Joinery's own CSS, as in an app: joinery/tokens.css and joinery/joinery.css,
 * which `pnpm site:css` copies in from the package's build, and which the theme picker swaps for
 * another base colour (joinery/themes/) and style (joinery/styles/). The site's colours are the
 * theme's tokens too, so the whole page follows the picker; only the brand's amber is its own.
 *
 * This sheet loads before Joinery's, to put the layers in order: the site's element defaults
 * (site-base) sit below Joinery's layer, so a component keeps its own look; the site's classes
 * are unlayered, as an app's own CSS is, and win.
