/* TWL Training Portal — glass-card theme, matching TalentLoop's manager_control.php
   visual system (Tailwind + Poppins + frosted-glass cards) for consistency across
   TWL's internal platforms. Component class NAMES are kept stable from the prior
   theme so every page built before this pass (reports/trainer/admin) picks up the
   new look automatically with zero markup changes — Phase 2 can migrate individual
   pages to raw Tailwind utility classes + .glass-card incrementally from here. */
