/* app.css - one small stylesheet. D-110: the "Fresh Air" look from the Lovable
   design (cream, deep blue instead of black, leafy green for actions), in hex so
   older Chrome on low-end phones reads it, with the green and red deepened until
   every text pair passes WCAG AA (4.5:1). Fonts are self-hosted in fonts/ (never
   Google's servers: no visitor IP leaves for a font) and swap in, so text shows
   at once in the system font on a slow network.
   Colour carries status on the people cards only; every status is also written
   out in words, so nothing depends on colour alone. */
