/** |

* StoreFaqContent — deterministic, store-aware Product FAQ generator. |
| 7 |
* |
| 8 |
* Single source of truth for the WooCommerce "sample Product FAQs" starter set: |
| 9 |
* four groups (Payments & Billing, Shipping & Delivery, Returns & Refunds, |
| 10 |
* Orders & Account) of three questions each, curated to cover the highest |
| 11 |
* friction pre-/post-purchase buyer questions. |
| 12 |
* |
| 13 |
* It serves two callers: |
| 14 |
* - SampleDocs::suggested_categories() uses definition() for the chips/titles |
| 15 |
* shown on the "detected profile" screen. |
| 16 |
* - SampleDocs::generate() uses generate() as the hybrid fallback when the AI |
| 17 |
* proxy is unavailable (offline / quota / no model), producing real answers |
| 18 |
* grounded in the site's actual store config (payment gateways, currency, |
| 19 |
* tax, shipping regions, return window, policy pages) — no AI required. |
| 20 |
* |
| 21 |
* Answers degrade gracefully: when a datum is missing, the copy falls back to a |
| 22 |
* generic-but-accurate sentence rather than inventing specifics. |
| 23 |
