/* ==========================================================================
   BACKGROUND PATTERN LIBRARY (in progress)
   Opt-in alternatives to .grid, built while exploring a replacement for the
   grid pattern on .hero and .final. NOT yet wired into any live page - the
   existing .grid above is untouched and still the default everywhere.

   Status: 12 of 13 confirmed and working (A-E, G-H, K, M-O, and the logo
   trace I). F (gyroid infill) is a placeholder only - the accurate woven
   pattern was not resolved and is still pending.

   HOW TO USE: each class below needs a matching HTML/SVG snippet placed
   inside the section (e.g. <div class="bgp-aurora">...</div>). See
   background-pattern-snippets.html for the exact markup to paste for each
   one. Apply on top of or in place of the existing .grid div.
