/* ==========================================================================
   Magalhães Advocacia — index floors (v2 · "A torre à noite")  ·  lighter pass
   Owned by the INDEX builder. Sits on top of tokens.css + shell.css + world.css.
   Every floor is transparent: the 3D world shows through. Content lives on
   glass, brushed metal, brass and black felt — objects inside the tower.

   Weight rules for this file: no backdrop-filter anywhere, no
   mix-blend-mode, no filter on moving things, no per-frame repaint — motion is
   transform/opacity only, infinite CSS animations pause when their floor is
   off screen (.is-off), glows are small and static.

   Contents
