/* ==========================================================================
   Tailwind CDN replacement
   --------------------------------------------------------------------------
   The site previously loaded the full Tailwind CSS framework at runtime via
   <script src="https://cdn.tailwindcss.com">, which ships the entire utility
   library and recompiles it in the browser on every page load. This file
   replaces that with hand-written rules for ONLY the utility classes this
   page actually uses (~75 of them), matching Tailwind's default design
   tokens exactly so the rendered output is unchanged.

   If you add new Tailwind-style classes to the HTML later, they will not
   work automatically — add the matching rule here.
   ========================================================================== */

/* ==========================================================================
   Minimal Preflight-equivalent reset
   --------------------------------------------------------------------------
   Tailwind's CDN script also applied a base reset ("Preflight") that zeroes
   out default browser margins on headings/paragraphs and normalizes
   buttons. This page's utility classes (mb-8, mb-4, etc.) were written
   assuming that reset was in place, so we restore just enough of it here
   for the handful of raw elements this page actually uses.
