# /iblai-vibe-monetization-subscription Wire the post-purchase surface inside the Profile page: a paginated, searchable list of the current user's subscriptions, a detail view per subscription, and a cancel flow that branches between an immediate cancel and a Stripe Customer Portal redirect. The SDK ships `PurchasesTab` — Profile renders it automatically when the Platform has monetization enabled — so most of the work is wiring, not UI. Do NOT add custom styles, colors, or CSS overrides to ibl.ai SDK components. They ship with their own styling. Keep the components as-is. Do NOT implement dark mode unless the user explicitly asks for it. When building custom UI around SDK components, use the ibl.ai brand: - **Primary**: `#0058cc`, **Gradient**: `linear-gradient(135deg, #00b0ef, #0058cc)` - **Button**: `bg-gradient-to-r from-[#2563EB] to-[#93C5FD] text-white` - **Font**: System sans-serif stack, **Style**: shadcn/ui new-york variant - Follow the component hierarchy: use ibl.ai SDK components (`@iblai/iblai-js`) first, then shadcn/ui for everything else (`npx shadcn@latest add <component>`).
