   Baby Junctions — Learning mode
   Loaded by components/header.php only when $bjMode === 'learning', layered
   over style.css. Two jobs:
     1. body.mode-learning re-points the brand tokens to the green-led "growth"
        palette so the header and every shared component follow without edits.
     2. The .learn-* classes that used to be duplicated inline in learning/index.php
        and learning/_band.php live here once, plus the pillar-block styles.
