/* ============================================================================
   FILE TYPE: Stylesheet: Upload Mesh product page (UM.74)
   INTELLIJ PATH: /TAGIIv4/webgate-src/uploadmesh/styles.css
   CREATED: 2026-09-04
   DAILY SESSION: docs/Daily_Sessions/2026/09/2026-09-04.md
   VERSION: 1.1.0
   WHERE (DEPLOYMENT): the webgate static stack; a page, no server side
   CONNECTS TO:
     - index.html (the only page that loads this file)
     - CLAIMS.md (the claim to evidence table the page is built from)

   WHAT: Tokens, layout, download cards and claim states for the Upload Mesh product page.
         No framework, no build step, no webfont request, no JavaScript.

   WHY:  The page ships on the webgate static stack. It must render from static local files
         and must read correctly in light and dark from the same tokens.
   ============================================================================ */

/* No webfont is fetched. Poppins is used when the host already serves it, otherwise
   the page falls back to the reader's system stack. */
