refactor: redesign landing page — break AI-template monotony, add FAQ, fix trust signals
Bold layout overhaul based on design critique:
- Left-aligned hero with two-column layout (text + app preview)
- Asymmetric problem section (headline left, cards right)
- Zigzag How It Works layout (alternating text/visual sides)
- FlowPilot highlight card + 3+2 feature grid
- New FAQ section (5 questions: ChatGPT comparison, data safety, PSA, sessions, AI accuracy)
- Founder quote replaces anonymous testimonial
- Removed ambient glow + grid pattern (design system violations)
- Self-contained color palette (--lp-* vars, no invisible text-secondary)
- 8px border radius aligned to design system
- Alternating section backgrounds replace divider lines
- Form: client-side validation, persistent errors, aria-live
- Skip-to-content link, semantic <main>, FAQ aria-expanded
- Pricing CTAs pass plan context (?plan=free|pro|team)
- Code elements in chat mock properly styled (JetBrains Mono)
- FAQ uses grid-template-rows for smooth height animation
