/* style.css
   Design grounded in the audience: elderly users, often low-vision,
   low digital literacy. One typeface (Atkinson Hyperlegible - built
   by the Braille Institute for low-vision readability), one screen,
   one job. Color palette literal to "Sky Blue": a clear-sky primary,
   a warm sun-glow used once as the signature element, and a distinct
   urgent color reserved only for "I need help" so urgency reads as
   color, not just text.
