/* ==========================================================================
   LM Book — Modern UI skin (added 2026-06-11)
   Global restyle layered on top of the Hyper (app-saas) Bootstrap 5 theme.
   Visual only: colours, spacing, radius, shadows, typography. No layout/JS change.
   Loaded LAST in header.php so these rules win.
