/* SurroundMe public site (surroundme.org). Warm-white and soft-tan palette,
   chosen for emotional warmth and for readers with visual disturbances: no
   pure white or black over large areas (less glare), text at 12:1+ contrast,
   SurroundMe blue at 7.5:1+ on the page (AAA), and a blue/warm axis that
   stays distinguishable in common color blindness. Sage is a soft tint only,
   never the sole signal. Plain HTML/CSS, no build step. */
