   KIRA RESEARCH — kira.css
   Design tokens + base + nav + footer + shared components.
   Page-specific styles live inline in each page file.

   THEME: Light editorial — white bg, deep navy ink, KIRA blue
   as restrained accent. Softened weights & shadows for an
   "analyst publication" feel rather than tech-startup energy.
