* Elementor compatibility – Assets & Body Class |
| 9 |
* |
| 10 |
* Ensures Elementor Theme Builder header/footer styling (kit typography, spacing, |
| 11 |
* Google Fonts) applies on all Yatra routed pages (trip, booking, destination, |
| 12 |
* activity, category and listing pages). |
| 13 |
* |
| 14 |
* Boot order: registered on `plugins_loaded` (priority 20) via Bootstrap so that |
| 15 |
* Elementor classes are guaranteed to be loaded before we check for them. |
| 16 |
* |
| 17 |
* === Font loading architecture === |
| 18 |
* |
| 19 |
* Elementor loads Google Fonts in two stages: |
| 20 |
* 1. CSS enqueue : `\Elementor\Core\Files\CSS\Post::create($id)->enqueue()` enqueues the |
| 21 |
* pre-generated CSS file AND queues each font in |
| 22 |
* `$frontend->fonts_to_enqueue` via `$frontend->enqueue_font()`. |
| 23 |
* 2. wp_head print : `$frontend->print_fonts_links()` (hooked by `Frontend::init()` at |
| 24 |
* priority 7) reads `fonts_to_enqueue` and outputs `<link>` tags. |
| 25 |
* |
| 26 |
* On Yatra pages (custom routing), Elementor does NOT detect the page as its own, |
| 27 |
* so neither step runs automatically. We trigger both: |
| 28 |
* – Step 1: call `Post::create($id)->enqueue()` for the active Kit and every |
| 29 |
* active Theme Builder header/footer template. |
| 30 |
* – Step 2: hook an explicit `wp_head` callback at priority 9 as a safety-net |
| 31 |
* in case `Frontend::init()` did not register its own priority-7 hook |
| 32 |
* (edge-case: some caching/proxy setups skip template_redirect). |
