/* Chelmsford Summer Series - 2027 priority access

   Layout idea: "the poster, then the form". The top of the page IS the
   client's poster - wordmark in the sky, the lit tree untouched in the
   middle, date and venue on the dark grass - and no text ever sits over
   the lights. The form lives on flat navy beside it (desktop) or under
   it (phone), so it is always read against a solid colour.

   Type follows the artwork: Instrument Serif Italic for the italic lines
   ("Summer Series", "August Bank Holiday"), Archivo for the heavy sans of
   the venue pill. Both SIL OFL 1.1, self-hosted. */
