| 103 | * `jetpack_search_blocks_enabled` feature flag — when off, the blocks |
| 104 | * don't exist at all. |
| 105 | * 2. Within this method, only the *template-takeover* surface (registering |
| 106 | * the Jetpack Search block template and prepending it to |
| 107 | * `search_template_hierarchy`) is additionally gated on the saved |
| 108 | * experience being `'embedded'`. Everything else — block registration, |
| 109 | * editor assets, and Interactivity API state seeding — runs whenever |
| 110 | * the feature flag is on, since admins can insert Search blocks |
| 111 | * anywhere blocks are configurable (post content, sidebar widgets, |
| 112 | * custom templates) regardless of which experience the dashboard has |
| 113 | * saved. Those blocks need the seeded base state (`apiRoot`, `nonce`, |
| 114 | * URL-derived `searchQuery` / `activeFilters`, `filterConfigs` slot, |
| 115 | * etc.) to hydrate; per-block `render.php` files only contribute their |
| 116 | * own config and rely on the global seed for the base. |
| 117 | * |
| 118 | * Why the template gate: with four experiences (`embedded` / `overlay` / |
| 119 | * `inline` / `off`), only Embedded should override the theme's |
| 120 | * `search.html`. A site that saves Overlay or Inline still expects |
| 121 | * `/?s=…` to resolve through the theme — the Jetpack template is the |
| 122 | * right answer only when the user has explicitly opted into the |
| 123 | * block-built search page. |
| 124 | * |
| 125 | * `Module_Control::get_experience()` reads `get_option( 'jetpack_search_experience' )` |
| 126 | * (object-cached) and falls back to deriving from the legacy booleans, so |
| 127 | * this is cheap on every request. `update_experience()` writes the option |
| 128 | * synchronously, so the next request after a save sees the new gate. |
