/* ============================================================================
   USETHEMARGIN, DESIGN SYSTEM (v2)
   ----------------------------------------------------------------------------
   Aesthetic:   Clean and white. Electric blue is the only accent; warm cream
                is used sparingly for one or two quiet bands.
   Corners:     12-16px on cards, images, buttons and inputs.
   Borders:     1px hairline, very light grey. No heavy borders, no offset
                shadows.
   Typography:  Inter everywhere. Climate Crisis is used for ONE thing only:
                the word "Margin" in the home page H1 (.hero__wordmark).
