/* ============================================================================
   Dear Enid — marketing site (dearenid.com)
   A calm, premium, trustworthy look: warm paper palette, Source Serif type,
   generous whitespace, soft shadows, one teal accent. Built to feel like a
   serious, well-funded British business — without stock imagery (photo slots
   are left for real photography). Single stylesheet, no framework.
