Contract-review SaaS with a redline pen that edits the hero live.

Build a SaaS hero for contract-review tool "QUILL" with React + Tailwind. Paper white #fbfaf7, ink #17161a, redline #e11d48. Fonts: "Source Serif 4" for the contract snippet, "Inter" body/UI. Hero center: a contract paragraph in serif that edits itself on a loop — strikethrough sweeps across "in perpetuity throughout the universe" (a red line-through animating width 0→100%), then an inserted correction "^ for 24 months" pops in above in red italic with a caret mark; two more edits follow ("indemnify" → "we'll discuss"), then reset. Headline above: "Your lawyer reads at 4 pages a minute. Quill reads at 400." Sub: "Flags the traps, drafts the pushback, bills you nothing per hour." Chips: "SOC 2", "8,200 FIRMS", "94% CLAUSE RECALL". CTA "Upload a contract" red pill + ghost "Watch the redline".legalredline
