   First Site Studio - home.css
   Homepage-only styles. Loaded on index.html after styles.css,
   so anything here wins over the shared rule of the same
   specificity. Nothing in this file is used by any other page.

   Direction: "solid ground". One bold move (a large geometric
   staircase in the hero, echoing the logo's first-step motif),
   then a calmer page below it: fewer boxes, fewer alternating
   bands, sentence-case eyebrows with a short sky-blue rule.
