| 3 | * openvibe-shared/vibes-pay.js — Vibes Pay for any page (MONEY.md, D12). |
| 4 | * |
| 5 | * <script src="https://openvibe.network/shared/vibes-pay.js"></script> |
| 6 | * |
| 7 | * <button data-ov-vibes-pay="https://openvibe.network/pay/vch_…">Pay with Vibes</button> |
| 8 | * |
| 9 | * OpenVibe.vibes.pay(payUrl).then(({ status }) => { … }); |
| 10 | * |
| 11 | * A button with data-ov-vibes-pay binds itself: it is styled as "Pay with Vibes" (the Vibes green, |
| 12 | * readable on light and dark themes), and a click opens the sheet in a popup on a computer and as a |
| 13 | * full page on a phone. The sheet posts { type: 'ov-vibes-pay', status, charge_id } to the page, only |
| 14 | * from https://openvibe.network; the promise resolves with { status } (and charge_id when sent), and |
| 15 | * a page may listen for the bubbling 'ov-vibes-pay' event instead. A popup closed without a payment |
| 16 | * resolves { status: 'closed' }. |
| 17 | * |
| 18 | * The sheet itself is openvibe.network/pay/<charge id>; a pay URL on another origin is refused. |
| 19 | * The button is progressive: without JavaScript (or this file) the link can still be a plain anchor. |
