Rules

• The banner reserves its height whether or not it fills. A banner that arrives late pushes the board down mid-game and costs a misplaced tap. Fill rates sit well below 100%, so the unfilled slot is the common case, not the edge.
• The interstitial never lands between the winning move and the winning line. It belongs after the result sheet is dismissed. Showing one before the player sees how they won is the most punished thing in this category's reviews.
• The store listings must say ads are present. An old listing draft once claimed "No Ads" while the production profile shipped both formats. The listing now has one source, .context/listing/listing.md.

Where it is drawn

The banner is a strip inside Home and Game, not a screen of its own — it is AdBanner, rendered under the scroll view on both. It was briefly drawn as three separate wireframes (banner, banner-empty, ads-off); none of those is a route the app has, and a wireframe of a component pretending to be a screen is worse than no wireframe.

Known gap

The interstitial has no wireframe, and the house rule is that a component in no HTML file does not ship. It fires after every third completed game, and its timing — never between the winning move and the winning line — is precisely the thing a wireframe would pin down. Recorded in routes.js and on the gallery rather than left silent.
