### Features
* 20+ configurable ad positions
* Popunder with cooldown and click threshold
* Exit-intent or delay-based popup behavior
* Global `` and `` injection fields
* Fallback HTML/JS ad code per position
* Minimalist inline CSS for fast load
* Responsive support for all device types
* Clean admin UI with media uploader
* Affiliate Gate with flexible display logic (always-on, expire-after-click, random%,
every X pages)
### Filters for Developers
* `init_plugin_suite_ad_engine_use_kses`
Control whether ad snippets are escaped
via `wp_kses`. Default: `true`.
* `init_plugin_suite_ad_engine_allowed_tags`
Extend or modify the allow-list of
permitted tags/attributes for ad snippets.
* `init_plugin_suite_ad_engine_disable_all_ads`
Disable all ad injections globally.
Default: `false`.
* `init_ad_engine_should_enqueue_affiliate_gate`

Gate scripts should be enqueued.
### Security Notes
* Ad snippets entered in the plugin settings are considered user-provided content.
* By default, all snippets are escaped at render time using `wp_kses` with a restricted
allow-list of tags and attributes.
* Developers can disable escaping via the `init_plugin_suite_ad_engine_use_kses`
filter if they explicitly trust their input.
* All ad injections can be globally disabled via the `init_plugin_suite_ad_engine_disable_all_ads`
filter.
* Only administrators with the `manage_options` capability can configure or modify
global ad settings.
