New onboarding, 4-step questionnaire + tinder-style post stack
Rebuilt /onboarding from scratch. The brand-kit pipeline now runs on a two-column layout: live progress on the left, a 4-step questionnaire on the right (Role · Goal · Vibe · Attribution). Pipeline answers feed straight into the strategist, so post output is tuned to the person, not just the brand. Reveal screen now shows a tinder-style post stack with a 4th locked card teasing what's behind the paywall.
