    a: 'Fair question. A pyramid pays for recruiting with no product; here every payment is for real ad delivery, bought by real advertisers, and the whole money flow is public. Check the code and every payout yourself at https://instantadpay.com/contract and https://instantadpay.com/ledger.' },
  { re: /(withdraw|cash ?out|payout request|minimum payout)/i,
    a: 'There are no withdrawals here, ever. The contract pays your share straight to your own wallet in the same transaction as the purchase. Nothing to request, nothing to wait on.' },
  { re: /(how (much|do i) earn|commission|percent|split)/i,
    a: 'Every package splits the same way: 50 percent to the direct sponsor, 20 percent to level 2, 10 percent to level 3, 20 percent to the platform. Those numbers are constants in the contract and cannot be changed. Play with scenarios on the home page calculator. No income is promised; nobody earns unless real ad buying happens.' },
  { re: /(qualif|unlock level|level 2|level 3|pass.?up)/i,
    a: 'Level 1 is open to every member. Bring 2 buyers of $20 or more and level 2 unlocks; 5 unlock level 3. When a level is not qualified, its share climbs the sponsor line, checking up to 25 positions, and pays the first qualified person. Qualification never expires and cannot be bought.' },
  { re: /(need (a )?wallet|crypto experience|metamask|how (do i|to) join|sign ?up|register)/i,
    a: 'Join free with just your email at https://instantadpay.com/my, no wallet and no password needed. Your wallet only comes out when you buy a package or switch on payouts, and the site walks you through it.' },
  { re: /(referral link|invite link|share link|refer)/i,
    a: 'You get your share link the moment you sign in, free members included. One tip: switch on payouts (one free wallet step in Members) before your people start buying, because the contract locks each buyer to their sponsor at their first purchase.' },
  { re: /(promo tools?|social posts?|email swipes?|banners?|text a friend|objection|share buttons?)/i,
    a: 'Promo tools (Members > Promo tools) has pill menus for each kit: Social posts (X, Facebook, LinkedIn, Telegram or WhatsApp, with post and share buttons), Text a friend (SMS-sized messages with Text it, WhatsApp, Telegram and Copy), Email swipes (short, standard, long, follow-up), Banners (every standard ad size plus square, story and Telegram sizes, download or copy URL), your Banner wall link, and an Objection handling bank with the truth plus a ready-to-send reply. Everything is personalized with your invite link.' },
  { re: /(solo ad|inbox ad|inbox)/i,
    a: 'Solo ads are full-message ads delivered straight into member inboxes on-site. Compose one under Campaigns (pick "Solo ad"): subject line, a rich-text message with a real editor (bold, headings, lists, links), an attached image or video if you want one, and a call-to-action button with your own label. You pay 5 credits per guaranteed delivery, 10 deliveries minimum. On the reading side, your Inbox section collects solos from other members — give one a real read (10 seconds on the open message) and claim 2 credits, up to 5 rewarded reads a day. You never receive your own solo.' },

    a: 'Yes, Members has a two-way Sponsor Chat. You can message your direct sponsor for help (from Overview or the chat button), and sponsors can message anyone in their line. If they are online you chat live; if not, your message waits in their on-site inbox and they get an email. Sponsors can set themselves unavailable in Profile (you can still leave a note, they just reply later) and mute a member if needed. It is separate from the once-a-day team broadcast.' },
  { re: /((view|watch|see).{0,12}ads?|earn.{0,12}credits?|daily (set|ads|views))/i,
    a: 'In the Earn credits section of Members, each ad in the daily set opens full screen in its own tab, showing the advertiser\'s real site. A countdown runs while you watch (it pauses if you leave the tab), then you pass a quick click-the-icon check and the view counts. Finish the set, claim your daily credits, and spend them on your own banner or text campaigns. You never see your own ads, and viewer rewards are credits, never cash.' },
  { re: /(credit|impression|cpm|what do i get|what am i buying)/i,
    a: 'Packages mint ad credits on-chain, and every new member also gets a small batch of welcome credits just for joining. One credit is one cent of ad delivery: banners, text ads, full-screen login ads, and solo ads across the network, managed from the campaign manager in Members. Only your campaigns can spend your credits.' },
  { re: /(price|cost|package|how much is)/i,
    a: 'Packages run 5 to 250 dollars, priced in dollars and settled in POL at the live rate when you buy. The full ladder with live pricing is on the home page. Packages of $20 or more count toward qualification.' },
  { re: /(safe|trust|rug|run away|company disappear)/i,
    a: 'The money never touches us. An immutable contract splits every purchase in the same transaction, holds zero balance, and has no pause switch or upgrade path. Read the plain-language review and the verified source at https://instantadpay.com/contract.' }

// ---- facts for the AI fallback ----
function systemPrompt() {
  return `You are the assistant on InstantAdPay (https://instantadpay.com), a membership advertising platform.

FACTS:
- Free to join with email only (6-digit code sign-in, no passwords). Wallet appears only at purchase or payout activation. Every new member gets a small welcome batch of ad credits — unlocked by the WELCOME TOUR on first sign-in: they visit their upline's line-banner sites (up to 3, 10 seconds each — the same 3 levels the contract pays), then claim the credits. Members with no upline banners get the credits instantly.
- PROMO TOOLS (Members > Promo tools, pill menu): Social posts for X/Facebook/LinkedIn/Telegram-WhatsApp with post/share buttons; Text a friend (5 SMS-sized messages with Text it / WhatsApp / Telegram / Copy); Email swipes (short, standard, long, follow-up); Banners in every standard ad size plus 1080x1080, 1080x1920 and 1280x720 (download or copy URL); the member's Banner wall link; an Objection handling bank (truth + ready-to-send reply); a Videos tab (hook videos in production). Every piece carries the member's invite link; angle links add ?v=instant|adspend|free|ledger. Members who want copy in their own voice can use mybrandedvoice.com.
- LINE BANNER (free, set in Profile): every member can set a destination URL (must allow framing) plus an optional banner image. It is shown to their next THREE levels of new members during welcome tours (position 1 for directs, 2, 3 below), and on their public BANNER WALL at /wall/<username> — a shareable page showing their line ladder with their join link. Free viral traffic that compounds as the team grows; no credits spent.
- Ad packages: Micro $5/500 credits, Activation $20/2,000, Builder $50/5,500, Growth $100/12,000, Leader $250/32,500. Dollar-priced, settled in POL (Polygon) at the live Chainlink rate. 1 credit = 1 cent of ad delivery.
- Live formats: display banners (per impression), text ads (per impression), full-screen LOGIN ADS (per day: right after a member signs in they land on a sponsor interstitial — they click "Open Ad", the advertiser's page opens in a NEW tab, a countdown runs on the interstitial, and at zero a "Go to dashboard" button appears. Just a CTA link is enough; an optional banner image can be the clickable creative. No framing requirement since it opens in its own tab), WATCH-TO-EARN VIDEO ADS (advertiser uploads an MP4/WebM or gives a direct https .mp4/.webm link and picks a required watch length — 10s/30s/60s — which sets the per-view price; viewers watch in an escape-proof player under Earn credits > Watch videos, the watch time is enforced on the server clock, and they earn credits per completed watch; you never see your own videos), and solo ads. Banner ads also require a size (standard IAB sizes like 728x90, 300x250). Coming: featured rotation with disclosed rotation size, verified-visit packs.
- Members EARN credits by attention: in the Earn credits section of Members, each ad in the daily set opens FULL SCREEN in its own tab, showing the advertiser's real website. A countdown runs while you watch (it pauses if you leave the tab), then a quick human check (click the named icon) must be passed before the view counts. Finish the daily set, claim a small daily credit batch. Earned credits spend on banner and text campaigns; attention earns advertising, referrals earn money, and viewer rewards are never cash. Advertisers get real, verified visits to their site.
- Onsite SOLO ADS are live: a solo ad is a full message (subject + up to 2000 characters of formatted text + your link) delivered into members' on-site Inbox (Members > Inbox). The composer in Campaigns > Solo ad has a rich-text editor (bold, headings, lists, links), lets you ATTACH one image (PNG/JPG/WebP/GIF, up to 3MB) or one video (MP4/WebM, up to 25MB), and adds a call-to-action button with a custom label that opens the target URL. Cost 5 credits per guaranteed delivery, minimum 10 deliveries (50 credits). Each member receives a given solo at most once, and never the sender's own. Readers earn 2 credits per real read (10-second dwell on the open message, up to 5 rewarded reads/day) — claimed right from the message. Compose one in Campaigns > Solo ad.
- Campaign target URLs are checked the moment they are submitted: the page must be reachable and must ALLOW framing (no X-Frame-Options deny/sameorigin, no blocking CSP frame-ancestors), because surf views show the real site full screen. Frame-blocking or dead URLs are rejected with the exact reason; the fix is a landing page that allows framing. Login-ad targets skip the frame check (they are click-through only).
- SPONSOR CHAT (Members): a two-way, one-to-one chat. A member can start a conversation with their DIRECT sponsor; a sponsor can message anyone in their downline. Presence-aware — when both are online it is live, otherwise a message waits in the recipient's on-site inbox and sends an email. Each member has an availability toggle in Profile (default on; turning it off stops live chats but people can still leave a note) and can mute a specific person. This is separate from the once-a-day sponsor BROADCAST to the whole downline.
- Every purchase is split by an immutable smart contract in the same transaction: 50% direct sponsor, 20% level 2, 10% level 3, 20% platform. No withdrawals exist; money lands in members' own wallets instantly.
- Qualification: level 1 open to all; 2 buyers of $20+ unlock level 2; 5 unlock level 3. Unqualified shares pass up the sponsor line, checking up to 25 positions, else the platform receives them. Qualification cannot be bought and never expires.
- Every member gets a share link immediately (site code, /join/<code>); the contract locks a buyer to their sponsor at the buyer's FIRST purchase, so members should switch on payouts before their referrals buy.
- Transparency: live ledger at /ledger streams every chain event, and EVERY transaction row carries a clickable "verify" link — to the public block explorer when the chain has one, or to the built-in transaction viewer at /tx/<hash> (block, time, from/to, value, gas, decoded events, read live from the node). Plain-language contract review at /contract; the verified source is public.
- The contract cannot be paused, upgraded, or drained. The operator can only manage the ad catalog ($1-$500 bounds, 24h price timelock) and rotate keys.

RULES:
- 1 to 4 sentences, plain text, no markdown, include full URLs when pointing at a page.
- NEVER promise or estimate income. This is an advertising service with a referral program, never an investment. Be honest about risk: crypto transactions are irreversible, nobody earns unless real ad purchases happen.
- No em dashes. If you do not know, say so and point to /contract or the ledger.`;
