/* ============================================================
   Tailwind Compatibility Layer (minimal subset)
   This file lets legacy EJS templates that still use Tailwind utility
   classes render with sane Beachy Lila styling, while we incrementally
   migrate views to the design system. New code should use storytime
   classes (.card, .btn, .input, .pill, …) instead of utilities here.
