/* ============================================================
   2 Steps Ahead Tutoring

   Taking the cues from the logo rather than from a template:
     - two pastels, lilac and mint, used together and in equal measure,
       the way they are in the mark
     - rounded, soft geometry (the footprints and the badge are all curves),
       so cards are generously rounded and buttons are pills
     - a chunky, friendly sans at heavy weights, matching the logo's ring
       text. A literary serif fought the mark; this agrees with it.

   The pastels appear as soft washes and fills behind dark text, never as a
   saturated stripe behind a headline.
