/* smaragd.sm0x.org — the site's own stylesheet.
 *
 * Every colour is a token from tokens.css or brand.css (both generated from
 * ../smaragd/brand/tokens.yaml). No literal colour lives in this file, and
 * bin/check.sh fails if one appears. Spacing, radii and motion come from the
 * same tokens; the type scale is the brand's, scaled up for a screen you read
 * at arm's length rather than a dialog.
 *
 * Two rules from DESIGN_GUIDELINES.md hold here as strictly as in the product:
 * turquoise means "you can click", orange means "attention" — and nothing else.
