   Singularity Hypertech — APPROACH PAGE sections
   Figma: Approach Page (1414:4184) — 1440x10624.
   Most of this page is assembled from sections that already exist:
     .brands / .cta / .orb*      -> css/shared.css
     .choose*                    -> css/home/home.css  (the four phases)
     .process / .timeline / .tl* -> css/home/home.css  (engagement models)
     .why-head / .dim2           -> css/home/home.css  (proven-results heading)
     .insights / .insight-*      -> css/shared.css     (latest insights)
     .ah-* hero orbit            -> css/hero-orbit.css
   js/main.js drives the choose scroll-spy, the timeline glow and the marquee.
   Only what follows is genuinely new to this page.
   Page-specific images live in /images under approach-*.
