/* ==========================================================================
   Live with Dora — editorial stylesheet
   No build step, no dependencies. Deploy as-is.

   Design direction: quiet luxury / editorial.
   Rules the whole file obeys:
     1. Hairlines instead of boxes. No rounded corners, no card shadows.
     2. Vertical rhythm is generous — sections breathe at 76–140px.
     3. Serif display type + neutral grotesque for everything structural.
     4. Exactly one accent colour (deep teal). Nothing else is coloured.
     5. Motion is slow and only ever opacity / colour / border.
