   /static/css/capsico.css ':root' (deep navy / dark steel blue palette),
   plus a dark-teal accent copied from an alternate palette already present
   in that same file. This file is intentionally standalone: it does NOT
   import/reuse capsico.css, so the product app (capsico.css) and this
   corporate site can evolve their palettes independently over time.
