   HERO — Premium Industrial Landing Split
   Isolated, additive layer on top of the existing .hero (kept exactly as
   defined inline in index.html: dark scoped tokens, grid shell, cursor-
   spotlight). This file adds the real furnace-floor photo (weighted to
   the right so it blends into the dark canvas rather than reading as a
   rectangle), the two-column content/visual split, the category badge,
   trust-logo strip, floating metric card and bottom achievement bar.

   No animation library, no Canvas/WebGL: every motion here is a CSS
   transition/keyframe, driven by a handful of classes toggled from plain
   vanilla JS in hero-cinematic.js.

/* ══ OUR BRANDS MINI SHOWCASE ══
   Each brand is its own standalone card rather than logos crammed
   into a shared strip: Elegant Steel and Thermocon TMT sit side by
   side on the first line, India Foils gets its own full-width line
   below. The card itself carries only a hairline border for shape —
   no fill/blur behind it — so the busy hero photo shows through
   cleanly instead of reading as a smeared dark panel. The white logo
   plate is the only opaque surface, sized generously (and per-brand,
   since the three source logos have wildly different native aspect
   ratios — Elegant Steel is a solid square, Thermocon/India Foils are
   wide letterboxed rectangles) so every logo renders at a legible
   size with room to breathe, never touching the plate's edges. */
