/* Scroll-tilt tablet for the #interface section of the landing page.
   Standalone and additive, same shape as bg-paths.v1.* and liquid-metal.v1.*.

   Why plain CSS and not Tailwind: this page's Tailwind output
   (index-DssA39eN.css) is a frozen build with no source tree, so a utility it
   never emitted does nothing. Every class below is defined here. The colours
   read the page's own :root tokens so the section stays on-palette.

   Geometry follows the ContainerScroll reference, retuned: 64rem scroll runway,
   1000px perspective on the stage, a 16:9 card, rotateX 20deg -> 0 and
   scale 1.05 -> 1 as the section is scrolled through. The transform values
   themselves are written by the bundle (ScraperShot) on rAF; the values here
   are the at-rest start state, so the card is never flat before JS runs. */

/* ---- liquid metal on the bezel --------------------------------------- */

/* liquid-metal.v2.js mounts the same animated rim it puts behind the dark CTAs
   on .ss-card as well. The base rules in liquid-metal.v1.css are scoped to
   [data-slot="liquid-button"] and are all pill-shaped, so the tablet needs its
   own geometry here. Radius is 26px: the card is 30px with a 4px border, and an
   absolutely positioned child at inset:0 fills the padding box.

   The canvas sits at z-index -9. A negative-z child paints after its parent's
   own background but before normal-flow children, so it covers .ss-card's #222
   and still sits behind .ss-screen. The #222 stays as the fallback for no-WebGL
   and reduced motion. */
