Balances: one reservation rule (earned first) + purchased-grade credited pool

- balances(): live campaign budgets are set aside up front, earned pool first then
  purchased, so dashboard numbers never move per impression; new 'in campaigns' line
- earned pool gains a purchase_grade portion for refunds/comps: shows under Purchased
  as 'credited to you' and funds login ads (daily login charge draws on it first)
- viewing credits always spend before credited purchased money
- dashboard/donut/spend banner/earn pane/positions show purchased, credited, earned, in campaigns
- chatbot canned answer + AI prompt: the balance rule

+    a: 'One rule: your balance is what is NOT committed to a live campaign. When you start a campaign its whole budget is set aside right then (earned credits first, then purchased), so your Available number drops once and then sits still while the ad runs. The budget spends down inside that campaign in Members > Campaigns, where you can see delivered views, network views and what is left. The dashboard shows Purchased available, Earned available and In live campaigns as three separate numbers; a paused campaign keeps its unspent budget set aside so it can resume. Nothing is lost when a balance reads low while a campaign is live. Purchased credits live on the blockchain; if we ever refund or credit purchased money it shows under Purchased as "credited to you" and spends like a purchase, login ads included. Earned credits fund every format except login ads.' },

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. Qualified Start: you may link extra wallets of your own as positions under your account (Buy packages > Qualified Start); each one that buys a $20+ package counts as a qualifying buyer, its credits pool with yours, and 50% of its purchase comes back to your main wallet. Your own money, your own wallets, a faster start, never an income promise.' },

 - 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.
+- BALANCE RULE (members ask this a lot): a balance is what is NOT committed to a live campaign. Starting a campaign sets aside its whole budget at once (earned pool first, then purchased), so Available drops once and stays still while ads serve; the budget spends down inside Members > Campaigns. Dashboard shows Purchased available, Earned available, In live campaigns. A paused campaign keeps its unspent budget set aside so it can resume. A low balance with a live campaign is not lost credits. Refunds/comps of purchased money are credited off-chain as purchased-grade credits: shown under Purchased as "credited to you", fund anything incl. login ads. Viewing-earned credits never fund login ads.
 - 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).
