/* ──────────────────────────────────────────────────────────────────
   Cook Impact Software — corporate site
   Deliberately distinct from Hawser (which is dark / teal / playful /
   app-like).  This is the PARENT COMPANY: light, editorial, calm —
   a serif display face + a deep-indigo accent on warm paper, the look
   of a small, serious software studio.
   Shared by every page; nav + footer are duplicated per-page (static
   site, no build step) but all styling lives here.
