| 82 | * Customizer v2 isn't enabled, the response has no style intent, or the intent sanitizes to |

| 84 | * |

| 86 | * (Sanitizer::sanitize_record()), so an AI style can no more produce an unsafe or |
| 87 | * tier-violating record here than it can through the customizer's own AI launcher. |
| 88 | * |
| 89 | * Also mirrors that launcher's honest-notice behaviour ({@see RestController::pro_locked_notice()}): |
| 90 | * unlike the standalone Style AI chat, this path used to strip Pro-only tokens with no |
| 91 | * explanation at all, so a free-tier form born from "create a sleek dark contact form" |
| 92 | * could render nothing like what the AI's own summary described. Sets |
| 93 | * self::$style_pro_locked_notice so EVF_AI_Ajax::get_pro_feature_notice() can surface it. |
| 94 | * |
| 95 | * Overlays onto the form's EXISTING style record exactly like the Style Customizer's own |
| 96 | * AI chat client does ({@see StyleStore.applyAiRecord()} in store.ts) rather than replacing |
| 97 | * it wholesale: the AI's output contract is strictly `{tokens, palette}`, so on a refine |
| 98 | * (update_form()) a straight option overwrite would silently wipe a previously-picked |
| 99 | * template or custom CSS, and treating an empty/omitted palette as "clear the palette" |
| 100 | * would incorrectly detach an existing one even on a turn where the AI never touched it. |
| 101 | * `$check_contrast = true` also matches ai_style()'s own sanitize_record() call, so an |
| 102 | * AI-created form gets the same automatic light-on-light / dark-on-dark correction the |
| 103 | * standalone chat already has. |
