/* Chelmsford Summer Series - 2027 priority access
   Palette sampled from the site's own dusk photograph of Central Park
   (fairy-lit trees, the lit viaduct on the horizon). Type is Fraunces +
   DM Sans - both SIL OFL, self-hosted - carried over from chelmsford.live
   so the page reads as the same brand.

   Signature element: the "horizon" rule under the title - a hairline that
   draws outward from a warm centre point, echoing the lit bridge at the
   photograph's vanishing point, carrying SEE YOU IN 2027 across it. */
