/* ──────────────────────────────────────────────────────────────
   Rideekanda Ecosystem Header  ·  eco-header.css
   One canonical top header bar shared by every sub-page. Namespaced
   `.eco-h*` so it never collides with a host page's own styles.
   Left padding clears the floating Explore launcher (eco-nav), so
   the Explore pill reads as the header's left-most control.
