/* Practical AI Community: the billboard. Same neutrals, type and radius as the
   free community's billboard (aass.community); its own accent: blue, not
   yellow, so the two sites never read as one. Light and dark, the system decides.
   The accent is never body text: always a field with its own text color on it.
   Accent pairs (the gate checks the ratios):
     light  field #1D4ED8, text #FFFFFF  6.70:1   field on page #F3F3F1  6.03:1
     dark   field #7AA7FF, text #0F1216  7.87:1   field on page #0F1216  7.87:1 */
