/* ============================================================
   Fleet landing — v2 light/dark band rhythm
   Loads AFTER styles.css. The ONLY change vs v1: alternating
   LIGHT "chart-paper" bands between the navy night-watch bands.

   Mechanism: a .band--light section REDEFINES the brand tokens
   (--ink, --muted, --teal-bright, --brass, --navy-2, --line …)
   in its own scope, so every v1 component re-themes for paper
   automatically — no component CSS is rewritten. Accents
   (teal/brass) are darkened just enough to clear WCAG-AA on the
   warm paper while staying the same brand hues.
   ============================================================ */

     #F4EEE0 to a deep warm sand/bone — closes the gap to the navy bands so
