Rewrite homepage — strip AI slop, cut to 5 sections

Removed: fake social proof numbers, testimonials (no clients),
pain/solution grid, trust badges, "why choose us", 11 sections
of repetitive centered-tag-title-grid layout.

Now: hero + product screenshots + module grid + differentiator + CTA.
Let the real product screenshots do the selling.
