/* ======================================================
   tailwind-shim.css — Minimal local replacement for the
   handful of Tailwind utility classes used on the CAC and
   LTV calculator pages. Replaces the prior runtime
   `<script src="https://cdn.tailwindcss.com">` dependency
   so those pages work with third-party CDNs blocked.

   Not a full Tailwind clone — only the classes actually
   referenced by cac/index.html and ltv/index.html, plus
   the small variants needed for responsive breakpoints
   (md:, lg:) that the source uses.
