/*
  theme-teal.css — retro candy: a deep, saturated teal background with
  a vivid HOT pink accent — deliberately not the soft pastel blush
  Bloom already owns. Dark bg + neon-candy accent is the opposite
  register from Bloom's white bg + gentle pastel, so the two shouldn't
  blur together even though both are "pink accent" themes. Lilita One
  (a single chunky retro-poster display face) over Nunito Sans. A
  touch softer/rounder than the site default, for a fun candy feel.

  The background is deliberately darker than the raw reference teal
  (#006b6b) — at that lightness, ANY vivid pink fails WCAG AA as
  accent-text (quiz timer, mark badges); lightening the pink enough to
  pass instead washed it out to a pastel, defeating the whole "hot
  candy, not soft blush" point. Darkening the background keeps the
  pink exactly as vivid as designed and arguably reads better anyway —
  neon-on-near-black rather than neon-on-midtone.

  Scoped under `body[data-theme="teal"]`, set at runtime by
  js/theme_switcher.js. 100% additive.
