/* ==========================================================================
   Chris the rainbow lover, main stylesheet

   Concept: a loud, cheerful comic-book fan page that someone has proofread.

   Palette (contrast checked against WCAG AA):
   --bg        #FFF8EC  cream page background. Ink on cream is about 16:1.
   --surface   #FFFFFF  quiz and log cards.
   --ink       #1F1A2E  text, the dark band and focus rings. About 16:1 on cream.
   --ink-soft  #4B4560  secondary text. About 8.6:1 on cream.
   --ginger    #C2410C  ginger accents and large headings. About 5.2:1 on white.
   --action    #5B21B6  buttons and links. About 9:1 with white text.
   --sun       #FFD60A  highlights on the dark band. About 12:1 with ink.
   Rainbow colours are decoration only. Body text never sits on them.

   Type: Lilita One for headings (chunky, a bit silly). Figtree for reading,
   at 400 and 700 only. Sizes are fluid with clamp().

   Motif: the rainbow arc. Six bands in order, used as the hero halo and
   as the stripe rules between sections.
