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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
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>

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.

The flex unit's expanded state renders into #pw-oop-flex_container, a direct <body> child. Body being a flex row squeezed it to width 0, so the unit could never show its expanded state or sense scrolling and latched permanently into the docked leaderboard. Body now wraps with the container ordered onto its own full-width first line: the ad expands (350px) at the top of the page, docks to the 100px leaderboard once scrolled past, and expands again on return. The content wrapper takes basis-full/min-h-dvh so it keeps its own line and full height now that align-content no longer stretches lines. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Invalidate queued gutter loads when closing.
adLoaded remains false until the queued callback runs, so repeated show() calls can enqueue duplicate spaAddAds() requests. close() destroys current rails but does not invalidate queued callbacks. A callback can therefore recreate the rails after close(). Track pending loads with a generation token and check the token before calling spaAddAds().

Docking emptied #pw-oop-flex_container (-350px) while the wrapper gained --top-ad-height padding (+100px), shifting the document above the viewport mid-scroll — and the shift moved the scroll relative to the dock threshold, so it could flip-flop. HomepagePromos now locks the container's min-height to the expanded ad height for the unit's lifetime, and page-content padding moved to a new --top-ad-pad var set only when a docked banner has no inline slot backing it (legacy #adBanner). --top-ad-height still offsets the sticky nav and mobile top bar, which are viewport-level and shift-free.

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.
