   AEC Wind — redesign prototype
   Design tokens first: change the brand here, everything follows.

/* ---------- fonts ----------
   Self-hosted rather than loaded from Google. That removes two third-party
   origins (and two DNS+TCP+TLS handshakes) from the critical path of every
   page, lets the Content-Security-Policy stay at default-src 'self' with no
   exceptions, and stops every visitor's IP being sent to Google.

   Both are variable fonts, so one file per family covers every weight we use —
   70 KB for the pair, latin subset. The pages preload them, so the swap window
   is short enough not to shift the hero headline noticeably.
   To update: re-download from Google Fonts and replace the two files. */
