 Giving `preload` a value of `none` tells the browser to not preload any of the video data before the user decides to play it, which is obviously good for performance. Instead, it will just show the image indicated by the `poster` attribute. Different browsers have different default video loading behavior, so it is good to be explicit.

 The [Private Aggregation API](https://developers.google.com/privacy-sandbox/relevance/private-aggregation) can use the Run output gate to process shared storage data and generate aggregated reports. These reports can be used in the following use cases:
 
-- [**Unique reach reporting**](https://developers.google.com/privacy-sandbox/relevance/shared-storage/unique-reach): Content producers and advertisers often want to know the number of unique viewers for their content. You can use shared storage to report the first time a user sees your ad or embedded publication and prevent duplicate counting for the same user on a different site, giving you an aggregated noisy report of approximate unique reach.
-- [**User demographic reporting**](https://developers.google.com/privacy-sandbox/relevance/shared-storage/user-demographics): Content producers often want to understand the demographics of their audience. You can use shared storage to record user demographic data on your main site, and use aggregated reporting to report on it across other sites in embedded contexts.
-- [**K+ frequency measurement**](https://developers.google.com/privacy-sandbox/relevance/shared-storage/k-freq-reach): Sometimes described as "effective frequency", K+ frequency refers to the minimum number of views needed before a user will recognize or recall certain content (often used in the context of ad views). You can use shared storage to build reports of unique users who have seen a piece of content at least K times.
