/*
  Elyndo website — one stylesheet for every page.
  Brand roles follow the app's Theme tokens: Midnight (identity, dark surfaces), Jade (actions,
  selection), Mint (hero moments), Canvas (light workspace), Amber (attention). Text colors are
  the app's AA-tuned text roles, so body copy keeps at least 4.5:1 in light and dark.
  Motion is progressive: content is fully visible without JavaScript, and every animation has a
  reduced-motion fallback.
