/* ==========================================================================
   Trabuco Creek Restoration Map — styles.css

   Look & feel: a digital field notebook / herbarium sheet that holds a live
   map. Plant data is set in a monospace "specimen label" style. Colors are
   drawn from the creek itself — willow green, iron-oxide red for invasives,
   and a steel-teal for water and accents.

   Built mobile-first (most viewing happens on phones), then adjusted upward
   for larger screens via the media query near the bottom.
