/* =====================================================================
   RENDER AI — Premium Multi-Page AI-Product Template (Themely)
   Text-to-3D model generator. Plain HTML5 + CSS3. No frameworks.
   Offline-ready: no external images (CSS gradients, inline SVG, emoji only).
   ---------------------------------------------------------------------
   REBRAND TIP: Change the brand look by editing the CSS variables in
   :root below. Swap --accent / --accent2 for your gradient pair, retune
   --bg / --surface / --ink for the theme, and update --font-head /
   --font-body plus the Google Fonts <link> in each HTML file. Everything
   else cascades automatically.
