/* ==========================================================================
   Training hub (/learn -> templates/page-learn.html, [learn_index]).
   Same design language as the support-guide index (sg-index): off-white hero
   with a big search, a "start here" path, rich cards, dark CTA band.
   EVERY selector is scoped under .learn-hub and lh- prefixed — the theme's
   bare nav/.hero/.step/.pill/.btn globals would otherwise collide (see the
   theme-global-selectors-collide note). Tokens alias theme.json presets.
