/* Shared front-door styling for the products sold separately from ClipLab.
   One file so Studio and Ads read as siblings rather than two unrelated sites.

   The look is glass over a dark, slowly moving ground: translucent panels with a
   real hairline edge and a light bloom behind them, the way Apple's material
   works. The trick that makes glass read as glass is the EDGE, not the blur, so
   every panel gets a bright top border and a darker bottom one. */
