   Kamal Mehta — Portfolio :: Signature layer
   -------------------------------------------------------------------------
   Everything that makes this site look like nobody else's: the live
   machine-learning canvas, the inference-lock hover, the co-pilot avatar,
   and the autoplay video treatment.

   Kept in its own file on purpose — if any of it ever feels like too much,
   removing one <link> tag and two <script> tags returns the site to the
   clean, conventional version underneath. Nothing here is load-bearing.
