/* Brand palette, sampled from the app icon (public/stayawakebot-app-icon.png), not guessed.
   The mark's mint is #80E1AB — 9.5% of the icon's saturated-green pixels, and its ground is
   #090E14. #80E1AB scores only 1.58:1 on white, so it is the DARK-scheme accent only; the light
   scheme uses hue-preserving darkenings of the same mint that clear WCAG AA for body text. */
