/* Homepage theme with two color modes: blue (default) and pink ([data-theme="pink"]).
   Hues come from a reference poster (pink #f3d9e1 / rose #e8b0b8, sky #a0d8f8 /
   blue #2878a8); page backgrounds are those hues mixed with 65 to 90% white. Text
   accents are slightly deeper so small text stays readable (>= 4.5:1).
   --swatch is the other mode's color, shown on the toggle. */
