Playbook: Add an outstream/sticky video unit

Playbook: Add an outstream/sticky video unit
What it does: drops in a video player for video CPMs without owning any video content.

Setup (effort 3/5):
— Use outstream (in-read) video, not a forced pre-roll — outstream pauses when out of view, protecting viewability.
— Place it mid-article in a high-dwell zone; video CPMs reward time-in-view.
— Make sticky-on-scroll dismissable with an X — non-closeable sticky video violates Better Ads Standards.
— Default muted with visible unmute; autoplay-with-sound tanks UX and gets policy flags.
— Reserve the player height; a video unit popping in is a large, late layout shift.

RPM lift seen: +10-25% page RPM where it fits — video CPMs dwarf display.

Pros: highest CPM lever short of owning video. Cons: heavy on page weight, real LCP/UX cost.

Lift: ★★★★☆ — Risk: ★★★☆☆
Best for: content sites with strong dwell time. Skip on lightweight/fast-bounce pages.
