/* WeatherSpirit — shared styles for every page on weatherspirit.com.
 *
 * ONE STYLESHEET, not a <style> block per page. The prototype inlines its CSS,
 * which is the right call for a single page and the wrong one for five: the
 * legal pages, the marketing page and the contact page would each carry their
 * own copy of the design tokens, and the first divergence would be invisible
 * until someone noticed the privacy policy was a slightly different grey. One
 * file costs one cached request and cannot drift from itself.
 */

/* ── Design tokens ───────────────────────────────────────────────────────
 *
 * The palette is the weather, not the brand. Photography carries every warm
 * colour on the site — a horse in golden light, a wet labrador, snow at dusk —
 * so the interface around it stays slate, straw and paper, and never competes
 * with the thing the product is actually selling.
