/* ==========================================================================
   michaelkipkorir.com — V12 layer ("Plain edition")
   --------------------------------------------------------------------------
   Loaded last. A plain, cool theme for the whole site plus the new homepage.
     A. Tokens — cool grey paper, ink, one cyan-blue accent, one typeface.
     B. Plain chrome — header, page heads, buttons, labels, cards, footer.
     C. Night theme tokens.
     D. Homepage — statement, record, areas, atlas, selected work, contact.
   Design notes: one typeface (Figtree), one accent, hairlines instead of
   boxes, and generous space. Motion is optional and reduced-motion aware.
