   Secret Santa: Christmas theme.

   Every colour is a token. Light is the default; the dark set (navy night
   sky, evergreen cards, cream text, cranberry and gold accents) applies when
   the device prefers dark. tests/test_contrast.py reads the tokens below and
   enforces WCAG AA, so keep them as plain #rrggbb values.
