/*
  Germaine Chin — quiet, text-first portfolio, pastel blue.
  Palette: White #FFFFFF · Mint Cream #EFFFFA · Alice Blue #E5ECF4 · Periwinkle #C3BEF7 · Medium Slate Blue #8A4FFF

  Light contrast on the lavender background (#E4E6FA): text 12.5:1, muted 5.4:1, link 5.2:1, white on slate-blue buttons 4.5:1.
  Periwinkle and raw Medium Slate Blue are used for decoration (rules, markers, focus, selection),
  except the large "chaos" letters, which only need 3:1 and all clear it.
