   CUPRUM LABS — styles.css
   ------------------------------------------------------------
   HOW TO EDIT:
   • Colors + type live in :root below. Change them there and the
     whole site updates. Nothing is hard-coded elsewhere.
   • Sections are ordered to match index.html (SECTION 1..12).
   • Discipline: warm neutrals do the work; blue (--glacier/--slate)
     is the one accent family; copper is a small metallic detail only.
