📝 What changed?

Rebuilds the landing page (docs/) with a more modern look.

• Look: near-black and white themes, with white primary buttons in dark mode and black in light mode, and blue kept for links and highlights.
• Header: a floating nav whose links follow the page order, with a Download button that also shows on phones.
• Hero: a left-aligned two-tone headline with shorter copy. The download button shows the visitor's OS logo and exact file, and the six engine logos sit on the first screen.
• Download section: even cards, each with one main build and its other formats listed below. The macOS card now matches Windows and Linux with only the universal .dmg as its main build.
• Tour: full-width cards whose screenshot alternates sides, with each card's label above its screenshot. On narrow screens the cards stack with the screenshot first.
• Features and pillars: icons sit beside their titles.
• Screenshots: a 4×3 grid of the 12 shots not already shown large. The lightbox still steps through all 15.
• Smaller fixes:
  • The opening statement is shorter.
  • The mac-style title bars are gone from the screenshot and code frames.
  • The AI tool list's spacing, which a stray indent had broken, is fixed.
  • The footer has link columns.
