/** |
| 3 |
* Storefront authentication REST endpoints. |
| 4 |
* |
| 5 |
* Mirrors the legacy `customer_login` admin-ajax action over REST so the |
| 6 |
* storefront login form (and any headless storefront) can sign a shopper in |
| 7 |
* via cookie auth without round-tripping through admin-ajax.php. |
| 8 |
* |
| 9 |
* Routes: |
| 10 |
* POST /wp-json/storeengine/v1/auth/login — sign in (sets the WP auth cookie) |
| 11 |
* POST /wp-json/storeengine/v1/auth/register — create account + sign in |
| 12 |
* POST /wp-json/storeengine/v1/auth/forgot-password — request reset email |
| 13 |
* POST /wp-json/storeengine/v1/auth/reset-password — finalize reset with key+login |
| 14 |
* |
| 15 |
* Uses the standard WP REST nonce (`X-WP-Nonce`) for CSRF protection on |
| 16 |
* same-origin storefronts. Cross-origin headless storefronts can't currently |
| 17 |
* authenticate this way (you can't set the WP auth cookie from another origin) — |
| 18 |
* that's a deliberate limitation; cross-origin clients should use the dedicated |
| 19 |
* application-password REST flow instead. |
| 20 |
* |
| 21 |
* The non-JS form-post handlers (StoreEngine\Post\ForgotPassword, |
| 22 |
* StoreEngine\Post\Register) call the same WP core primitives this controller |
| 23 |
* does — both paths converge on retrieve_password() / wp_create_user() / |
| 24 |
* reset_password() so behavior stays identical regardless of submission style. |
