Move scrolling from an inner container to the window itself, which GumGum header ads require for viewability tracking. In-game the page stays locked via a body.in-game rule (the game canvas is fixed and pans itself). The desktop nav becomes sticky so it stays visible while the page scrolls.

The Playwire flex leaderboard (GumGum header) is an out-of-page unit: ramp.js nests #pw-oop-flex inside a #pw-oop-flex_container body child and docks it fixed at the viewport top with an inline max z-index, covering the menu bar. HomepagePromos now observes the banner and exposes its docked height as --top-ad-height on <html>; the sticky desktop nav, home content wrapper, and fixed mobile top bar offset by it, and the space is released when the unit collapses or unfills. Its z-index is capped to 150 (bottom-rail convention) so modals and the mobile drawer stay above it. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Observe the Playwire wrapper position changes.
Lines 34-37 state that Playwire nests #pw-oop-flex inside #pw-oop-flex_container. This observer watches only the child. If Playwire sets position: fixed or changes top on the wrapper, neither the child ResizeObserver nor this observer runs. --top-ad-height can remain unset while the ad covers the navigation and homepage content.
Observe style and class changes on #pw-oop-flex_container in addition to #pw-oop-flex. Continue to measure the inner element.
Proposed fix
this.topAdStyle.observe(el, {
attributes: true,
attributeFilter: ["style", "class"],
});
+ const flexContainer =
+ el.id === "pw-oop-flex"
+ ? document.getElementById("pw-oop-flex_container")
+ : null;
+ if (flexContainer) {
+ this.topAdStyle.observe(flexContainer, {
+ attributes: true,

Description:
Two-part change enabling GumGum header ads on the homepage (served via Playwire as the out-of-page
flexleaderboard):1. The homepage now scrolls at the document level. Scrolling used to happen inside a nested container (
MainLayout'soverflow-y-autodiv) with the body locked byoverflow: hidden !important. Ad viewability tracking needs real window scrolling, so the body now grows with content and the document scrolls. In-game is unchanged: abody.in-gamerule re-locks the page (the map canvas is fixed and pans itself). The desktop nav becomes sticky so it stays visible while scrolling.2. The page makes room for the docked header ad. The flex unit is out-of-page: ramp.js nests
#pw-oop-flexinside a#pw-oop-flex_containerbody child and docks itposition: fixedat the viewport top with an inlinez-index: 2147483647, so the page reserves no space and the ad covered the menu bar.HomepagePromosnow observes the banner (childList+subtree MutationObserver to catch injection, ResizeObserver + attribute observer for dock/park/collapse transitions) and exposes its docked height as--top-ad-heighton<html>. The sticky desktop nav, home content wrapper, and fixed mobile top bar offset by it; the space is released when no ad fills. Its z-index is capped to 150 (same convention as the bottom rail) so modals and the mobile drawer stay above it.Ads remain homepage-only per the existing gating; nothing changes in-game.
Verification
in-gameclass fully locks scrolling, footer reachable at page end.ramp.spaAddAds({type: 'flex'})in a headed browser, since RAMP won't initialize headless): banner docks at 0–100px,--top-ad-heightreads100px, nav sits at exactly y=100 at rest and while scrolling, gutter ads and corner video unaffected. Collapse/removal releases the offset.Please complete the following:
