   The palette is chosen on <html data-palette="..."> (see config/site_flags.py). Every
   color pairing below was checked against WCAG AA: body and muted text on the backgrounds,
   button text on the accent, white on the anchor, and accent-text on the backgrounds
   (and over the hero's glow). --field-line, the edge of a text box, and both focus colors
   are at least 3:1 against what sits next to them (WCAG 1.4.11). */
